Neither will happen, the PS4 has killed off the PS3's momentum and PS3 has hit it's lowest profit/sales balance point, and price cuts will not generate sufficient sales to counter the lower profit. Wii U will probably be flat YOY at the end of this year but I still see it's replacement hitting in 2016 and Wii U sales will collapse after that.
PS3 will prob end up at 90mil, and Wii U at 15 million.
