I know if I was in the market for a new C I'd definitely wait for the V8. We're deep into the 2,000s & engineering / manufacturing of internal combustion engines has arguably never been better. Lots of experience & LOTS of computing power running design & construction make it so. I don't worry about '1st year stuff' like I did 2-3 decades ago.
IMHO Ford's had a really good track record with the last few truck engines they've rolled out, right from the starting block e.g. 3.5L EcoBoosts & 6.7L Powerstroke to name 2 of them.
