Thats quite possible, its at double the sales now so the PS4 would just need to keep doubling the XB1's sales and it'll get there. Things that will make that difficult will be holidays (PS4 is more likely to be supply constrained than XB1, which may lead to lost sales in peak periods like Christmas) and possibly China (if that takes off and Sony delay their entry into the market too long). I'd give the PS4 a 70% chance of achieving it.
