Personally (and I have no info to back this up) I think the V8 will be around, just alot smaller cu in wise and use forced induction for big HP. I'm kind of leaning towards a 4.8 litre V8 Pentastar, extrapolating the 3.6 's #'s, a 4.8 would be a tick over 400 HP, not bad. And this isn't with direct injection. The 8spd would be perfectly matched, low torque peaky motors like lots of gears to keep them in the power band. Or maybe it's just wishful thinking
I know Chrysler said the V8's time was limited but that was made during a recession and bankruptcy, alot has changed since then
