It's all depend on when Nintendo will replace Wii U with their next gen console. Because for what we know,Nintendo system never had a long life support like PlayStation. It's a marathon now, because both system will not have any major big push even with exclusive games.
Wii u actually able to prolong it's life by releasing slimmer Wii U, but slim version of Nintendo console always come if their console is a major success like SNES and Wii, so i doubt that scenario will happen either.
and for Vita it will not gain any more push then the previous sales, it's life will only depend on how long Japanese third party support it, if it dead before Wii U successor release then Wii U wins, if not then Vita wins.
