I only know one thing and that is GM is going to do something in this area. We just don't know what it is yet. If we only go by what we know, the engine will be the LT4 because that is what is in the top shelf world beaters GM has already shown us. It is also very easy for GM to hide engine development. Partly because it can be hidden in dyno cells and under the hoods of non descript cars you wouldn't even notice. The purchased parts are much more limited and leaks from the supply base are less likely.
So can I imagine 2 cars with the LT4, one track focused, the other street focused? Yes, I can. And if I were in charge and didn't have the capital for a unique NA engine, that's just what I'd do. And I would do so knowing I would crush the GT350R with ease and only worry about the GT500 making Hell Cat HP.

The 5.2 is hand built, just like the LS7, except for the titanium parts and the dry sump.
If GM does go with the LT4 for a Z28, I hope they get the cooling right.
