I remember last week: Best Buy, Target Wall Mart, Gamestop, Sony, Amazon all had ps4 available. But now it's all gone except for wallmart...

The hype for the PS4 is just crazy. And Japan launch is getting closer.
I honestly though that 2 weeks ago we had the last : "PS4 available in best buy now" or "PS4 available in amazon now" threads.
Edit: Sold out in Wall Mart now. And just got available on amazon for 9 hours now. 6:00pm February 12
