So worth it to buy a $200 piece of hardware to keep tabs on another one worth $400. PSVita is better than 4 as of now though.

That makes the PS4 a $600 version of what the WiiU does more or less.

Could be a good thing for "second-screen" gaming though if it takes off. Maybe the effects rub off onto the Wii U. But I don't see that happening.

I have answered this many times along with everyone else with basic common sense in these forums. You obviously just keep missing it.

Yeah I never saw anyone make that  crazy of a prediction before here or anywhere else.

Off the top of my head i can name 3 users who have had such a predictions, and not just 2 years ago when stuff like that was more acceptable, but very recent as well, ninetailschris, Zero999 and DevilRising have said this.

According to this site they sold basically the same amount last year with Wii U slightly ahead, it doesnt matter that Vita outsells it on a typical week if Wii U is able to soundly beat it over the holidays.

Probably a few weeks this year.

It depends on how much soundly: between 23 Nov and 28 Dec 2014 Wii U was able to beat PSV by ~490k, then, since the beginning of January, PSV started beating it almost every week by between a few k and a few tens k. At this pace, admitting the yearly balance even be in Wii U's favour, it will take years to fill the gap. Gap that at the end of Dec 2013 Wii U managed to shrink to less than 1.9M and now is already above 2M and slowly crawling up.

Well, I'm pretty sure the vita tends to sell more weekly and it got a 9 month head start, so I think you can do the math.

Go back and look even further. At the end of 2012 Vita had a 1.9m lead and outsold Wii U most weeks in 2013. Wii U had a better holiday and was able to erase the lead Vita accumilated over the non holiday months bringing the gap back to 1.9m. The same is likely to happen year, Vita winning most weeks due to solid sales in Japan with Wii U having a better holiday.
