It's just the games that push them up and down. Both consoles will be selling a steady amount at the moment.

Yes, For poeple who use a Wii U or Xbox as their main/only console SFV isn't going to make them go out and buy a PS4 and I think that the userbase that will buy SFV already own a PS4.
Well Killer Instinct is very little compared to SF V to say it would suffice to keep people from deciding to buy X1 instead of PS4 or go multiplat.
