6 months after. I don't do day 1. I have $ for the PS4 and about 10 games already and I plan to save up to get more (I'm getting all cross gen games on PS4). inFAMOUS might encourage me to get it sooner, but I'll do my best to stick to my 6 month rule.
Playstation = The Beast from the East
Sony + Nintendo = WIN! PS3 + PSV + PS4 + Wii U + 3DS
