The LS9 is too expensive. (Would make the Z28 ~$50,000) and the LS7 is on its way out of production(this 427 SB is one of my favorites) which leaves the LSA.
Unless they can bring an awesome DI Gen V out in the next year (probably pretty doubtful, but I have hope).
I will wait for the Gen V introduction in the Camaro before I buy one because that's how long it will take me to repay my student loans.
