According to Sony there might be periods between now and April where availability on dealer shelves might be a little better, but ample inventories on dealer shelves should not be expected till April. The success of the PS4 has exceeded even Sony’s high expectations according to reports.
As of the second week of February, Sony has moved around 5 million consoles which is ahead of the Xbox One, but the tables might turn as the Xbox One prepares to receive Titanfall which is the first major excusive title for the platform. According to sources, Sony quietly has apparently expressed the opinion that Titanfall is not likely to impact their sales of the PS4 over the longer term, but it is possible there could be some impact, but with inventory availability tight, the timing might just actually work out for Sony.
