Latest Generation of GM Trucks and Full Size SUVs

Just wondering if anyone is privileged enough to have seen any of the latest GM full size trucks and SUVs? I have been considering purchasing a new Yukon of Denali. However, I would like to see the next generation. Anyone have any pics.?

There are some floating around the web. They are sharp imo.

There were some pictures floating around, but they got yanked pretty fast.

Assuming I like the exterior of the new trucks/SUVs... I think they'd be hard to pass up over a current version, if for no other reason than I really really dont like the looks of the current dash board. (Though crazy rebates to move out the old ones may make then impossible to pass up based on value.)

The current dash is not a hurdle I couldn't get over though..... Avalanche and Silverado SS and even Escalade, EXT, and Yukon Denali are on my "maybe" lists after the GTO's lease is up.

Though TrailBlazer SS has worked it's was up the list recently.

I saw the pics of the new full size SUV's... the front of the Tahoe looks very nice. The Avalanche pictures I've seen look very clean, though I was one that liked the current cladded version... also, word is Avalanche will share front ends with Tahoe, so that makes it less of it's own model to me... I liked a unique front end. The rear of the Tahoe/Escalade looked nice too... though there was a big piece of chrome trim I wasn't crazy about on Escalade. Haven't seen enough of the Yukon to comment on it.

Do we know if they are getting DOD on any of the engines?
