I think the gap is equal to Xbox-PS2 ( it was a big one) , the gap between PS3-360 game was not that big, except for maybe 5 games ( bayonetta,...)
ITs the first time in history that we have a more powerful system, cheaper and easier to develop for at the same time.
PS4 is in a very good position, Xbox One is in the worst position ever, from this pov.
Predictions for end of 2014 HW sales:
PS4: 17m XB1: 10m WiiU: 10m Vita: 10m
