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.
If they are into fighting games, Street Fighter V will be the time they purchase the system. To many fighting games are PS4 exclusives to pass up the PS4 including King of Fighters, Guilty Gear, and more.
