They're also rumoured to be capable of supporting a 3 valve cam-in block design, something which was proposed for the gen IV's (namely the LS7) but never came to fruition. Time will tell if its been abandoned again or not. But the point is, if they are working on those sorts of things (and who knows what else) then I'd say that the Gen V is a ground up redesign and not just a small update like the Gen IV's were.

They've already invested nearly a billion dollars into the program, including plant retooling at multiple locations. It's real enough...they keep referring to a "revolutionary new combustion process".
And they intend to maintain the same bore-center spacing dating back to the very first Chevy Small Block. GM has several interesting press releases out on the engines that are decent reads.
