The ps3 was still selling 2.5 times what the wii u is every week prior to price-cut. I still think ps3 has enough price cuts left and continued support to pass wii.
The initial week of the ps3 price cut was over 550k ww, there was a lot of pent up demand for the system, and the only thing holding it back was its price. even then, people were still saying ps3 would never pass n64 in sales.
