I think it's safe to assume that GM is learning quickly from past mistakes and as such we'll see the Camaro looking pretty close to it's original concept, and while it's a bit early to know for sure I think the Beat will be the same. Taking that into account GM would be mad not to show this as a motorshow concept before ushering it into production. With rising fuel prices and CAFE considerations the Corvette is really only going to become a niche vehicle (moreso than it already is) which is a great opportunity to make it really stand out, push the boundaries with it and make it a true halo car for the brand.
I can't say I'm a huge fan of the four centrally mounted exhaust outlets, but thats just me and who knows what revisions could be made if this was destined for production. The rest of the car though is a winner in my eyes. It neatly invokes the themes of the legendary 1960's Vettes while still looking modern and cutting edge. I say bring it on, and in honour of getting things right, engineer a RHD version too!
