PS4 passing 100M to me is a no brainier

the reason why PS3 is having a hard time/couldnt get pass 100M is b/c 360 and even the wii took loads of sales from it aswell as having a rough start form launch till about when UC2 release the ps4 wont have these issues its the it console this gen

The PS3's rough start sold better than the PS4's awesome one, though. How is that hard to understand?
