Yah, Alpha platform will kinda be like Infiniti's FM platform.
There is a good chance that the Camaro variant will be a lower-cost unit. GM is pouring a lot of money into the Alpha Caddy, known as the ATS, to nail the handling better then the 3 series or G35. They are really focusing hard on the steering feel and ride.
Camaro gets an update for 2011 with the convertable.
Alpha was originaly not designed to handle a V8. Its always been a question if Camaro will move to Alpha or something similar, say a lightened version of what it has now, or somthing from Holden.
Holden is also currently working on its next-generation platfrom, to go smaller to meet teh need for lighter cars as most of what they do is exported to other countries.
And of course Holden will not walk away from the V8. So its a coin toss at this point.
