Yup, noticed Best Buy both the website and pretty much all local Best Buy stores in my region (8 out of 10) have PS4 in stock now. Along with still Amazon for about 6 days now.
Truly large shipments have come, lets see if they last. March should at least give somewhat of an idea of a non supply constrained PS4 sales (not to say it cant slip back into constraint).
If they dont have to worry about Japan any more (now probably down to a 25k/week 100k/month sustained pace) and I imagine there's no large markets left to worry about launching at, then they should be able to focus their 1 million a month or whatever on USA/Europe and we should get into stock.
Sony will then be challenged if they achieve stock, to stockpile before holidays.
