I think Sony will do great this holiday, as well as MS. Nintendo has a chance to prove itself (I really hope it does) this holiday. I really hope all three companies do well this gen because all that means is more games for me.
I would also like to comment on some comments i saw earlier in the thread but didn't feel like reading everyone's reply. Sorry if it was posted already. But to those talking about install base and what not, especially when it comes to Watch Dogs PS4 vs XB1, if you do some math it looks like exclusive marketing does make a difference (or at least it just sold better).
USA data where the gap is smaller.
2,867,177 Systems / 590,488 Watch Dogs' Sales
3,455,879 Systems / 976,858 Watch Dogs' Sales
1 in every 4.855 XB1 owners bought the game.
1 in every 3.537 PS4 owners bought the game
Meaning that if both of these systems had the same exact install base (XB1 for example) of 2,867,177.
2,867,177 / 3.537
So the PS4 Watch dogs still would have sold theoretically 810,624 vs 590,488 for the XB1. So roughly around 220,000 more copies minus the consoles sold gap.
So tell me again how install base vs exclusive marketing / content works again? Otherwise why would any company even bother with exclusive marketing if it had no effect. And yes a multiplate can effect which console a person buys. I bought an Original XBox and sold my PS2 when i was younger because of the graphical and performance difference between exact titles (I was also a kid and couldn't afford both consoles at the same time).
