I'm guessing 3.3L max and 450 HP max.
Today's game is about weight reduction and fuel economy.

Time will tell. Let the wait begin.
Not only is horsepower relevant - buy also look at how the s63tu has such a huge power advantage at speed versus the s85 - s85 didnt reach peak power until 7750 rpm, at which point the hp starts to go somewhat back downhill again. With the s63tu, you're at 560 hp from roughly 6000 rpm to about 7000 rpm!! Presumably the next generation m3 engine (whether I6 or V6) will also have peak hp and torque over a broad range of rpm's - which in turn means a significant increase in performance beyond what the numbers themselves suggest.

Take the F10 M5 - it has "only" 60 more peak hp than E60 M5 - which doesn't seem like that much. You then take the 200 lb greater weight of the F10, which would seem to further diminish the 60 hp advantage - therefore - the power to weight ratio of the F10 v the E 60 is not much better at all. But nevertheless, the performance advantage is far more significant that the power to weight figures by themselves would otherwise suggest.
