Chevy would never change the name of their new toy when all the info has already been released, magazine reviews completed and cars about to be shipped. They even have the '13 ZL1 vert officially announced, so don't hold your breath on the name change. I think the ZL1 will do just fine once the GT500 comes out, even if it's slightly slower, I think there is more technology in the ZL1 and if you want a faster, be prepared to go broke cuz there will always be somebody faster than you with a bigger wallet to make it happen
