MCM is stone DEAD. Long live .......  

Heath, Its all relative. (?)
After a "super-nova", its hard to see those other faces of Modernism as not derivitive (if you can see them at all)
My retinas are seared from the glare of the mid century, and rightly so?
Just my own feeling about it of course, but most of the recently designed stuff just feels redundant--  a variation for the sake of variation, and still leaning quite heavily on many of the design INVENTIONS (in both form and function) that nailed it so well in the mid century.
Your depth of awarness of all that has been done in recent years is very impressive. I should get out more.
Not answering for KeeWee here, just felt that the Igloo comment might apply to me also! haha

I could be wrong but the correct term should be "mid-20th century modern" now that we are in the 21st century.  I remember when I first encountered that term "mid-century modern" was back in 1986 when Cara Greenberg's book came out with the same title and at the time the only new book I know of that was comprehensive and detailed enough to tackle the subject during the time when the 1950's was retro and there was really not much written about the subject and it was considered the bible for early collectors. 
At the time too, it was not the good 1950's that was retro, it was more the kitsch and popular culture (pink flamingos, tail finned cadillacs etc.) that influenced most of what was happening in the 1980's. (remember the B-52's or even the brithish boy band Depeche Mode/Elvis, Brando, Buddy Holly lookalikes in Goth?).  Pink with black/dark grey or turquoise with yellow, peach and mint green are not post-modern/Memphis color schemes, just look at the mix and match colors of Russel Wright's 1946 dinnerware for Iroquois china and don't forget that the burger chains like Johnny Rockets and Planet Hollywood were born in the 1980's inspired by the American diners jukeboxes, chrome and vinyl furniture, milkshakes and watresses on roller skates).  I don't know the answer why MCM (or whatever) still persists today when I thought it was pretty much over back in 1998 like those ubiquitous stainless steel appliances that everyone seems to want today.
sorry off topic:
Call it paranoia in the digital age but I will not post any pictures or snappies online ever. And Gropius, not to elaborate, but yes they are real because I know my stuff and owning replicas, reproductions, reissues just seems contrdictory to me why I re-use or re-purpose vintage stuff.

Who knows whit criteria will be in action 40 years from now? Function, easy repairability? Its possible that having a conspicous display of a collection might be seen as a bit vulgar if things really go pear shaped.  
Anyway revivals and derivations remain valuable for all sorts of reasons, would anyone dismiss Morris?

Heath-No. Not at all. But none of it was/is produced in very large numbers. MCM was for the masses. A lot of the future collectible stuff now seems a bit...boutique. Some of the other stuff seems as others have pointed out...variations.  I don't think any of it is around in sufficient enough numbers to insprire a wave of collecting later. Not that it won't be collected by some. But overall...some of it is missing je nais se quoi. Some of it is just over designed attempts at being modern.
But when talking about the collectibles market in general, I think most would agree- especially Hannibal Lector-we covet what we see. People end up collecting something they might have gotten a whiff of somewhere in their childhood. All of those are good brands, but I'm not sure that people are seeing them around enough to want to collect them later. They haven't entered popular culture in the way that MCM of the past did.

Remember how wrong Fukiyama was, things change. 

A lot of people thought the end of the show Mad Men in the US would slow the MCM market down but MCM was already popular before this show aired. I think MCM is still doing very well and all the manufacturers and shops including even middle of the road companies like overstockeddotcom are producing MCM clones. There are furniture shops in NY and LA like Thrive that do nothing but make brand new MCM furniture. It's also heavily featured on Elle Decor on a monthly basis. I don't think it's going anywhere and aesthetically speaking it may turn out to be the most timeless style ever (that's my opinion anyway).

That's the way it looks to me.  Maybe it's a San Francisco thing ? (Just kidding.)

Even middle aged hausfraus like it! But a couple of yeas ago they liked "french provincial" crap and dutifully distressed their mlik paint and hung lavender all over the place.
A renewed Georgian influence, that would be a pleasure to see.

Even for a new collector, the decision to collect only vintage pieces helps to reinforce the idea of restraint. Not always being able to get what you want gives one an appreciation of rarity, and makes the occaisional find that much more satisfying.
The accessablity of endless knock-offs allows one to easily hoard copies of anything and everything, until nothing means anything. Aside from the quality issues (which are very significant) everything becomes equally UN rare, and the whole idea of the hunt goes flat. 
I have wanted a polygon clock for over 10 years.  I have had only one chance at one in that timeframe, but it was WAY too expensive. I may never be able to find one I can afford. But to buy a knock off would render the whole process meaningless.
If I opened the knockoff floodgates, I would probably have 20 to 30 MORE Nelson clocks right now. The price barrier is all that has kept my obsessive collecting in check. 
Restraint is a good thing.
