I don't think it's terribly likely that a Z28 will be produced on the Zeta platform, but that's only my opinion. That's one of the reasons why I'm going to purchase a 2013 ZL1 (besides the fact that I think that the ZL1 is one of the type of vehicles that I have dreamed of owning), as I'm getting too old to wait for a Z28. However, if a Z28 is produced, Zeta or Alpha (which I think is more likely given the design parameters) I will purchase one, as the first gen Z28 concept is one of the types of vehicles that I have really wanted since the 5th Gen Camaro concept was unveiled. I know that a new Z28 will never be quite the same as a first gen Z28, and that one can never truly go home again, but the type of vehicle that first gen Z28 represented is a concept that, I think, that is still a vehicle that has a viable market, and would be a well received vehicle, even if it doesn't have a solid lifter 30-30 cam.
