The LS2 is just for the concept car and we will not see it in the production Camaro.
No word yet on what will be in the production Camaro though.
LS2 has been in the Corvette since the 2005 model.
And starting with the 2008 Corvette, it gets the LS3.
If history is a lesson, then we can speculate that the LS3 would show up in Camaro too, however this is purely speculation.
