PS4 has already outsold the WiiU in USA in 2013 sales.

Well there you go. So it's about 3-1. Looks far less impressive than ".. so in a matter of 24 hours PS4 almost doubled what the WiiU sold all year in usa"

It really doesn't make much of a difference, chances are in a couple months time people will be saying "outsold the wiiu worldwide lifetime in less than 3 months", the scale isn't so important, in that sense.

Perhaps. But I would be careful to draw future trajectories based on launch numbers - the Wii U and the Vita both showed us that a good launch does not equate to sustainable sales.
