My guess would be that it depends on the production numbers.
I expect both the PS4 and the XB1 to be sold out for Q4 2013 and quite possibly through Q1 2014, if not, extremely supply restricted.
So... it really depends on whether SCE or MS can produce more hardware units or at least more units than Nintendo has sold to date to take the fairly irrelevant title of best selling console of the 8th generation.
