I would love to have a 3DS for Fire Emblem and Bravely Default, but I'm just not going to get another handheld.
With home consoles, I'll be honest, I'm not buying anything until after the PS4/720 are out and we know everything about them. Even then, unless Sony screws up badly, I'm anticipating getting a PS4 because I'm a fan of Worldwide Studios.
The best chance for me to get a Wii U would be as a second console somewhere down the line. As of now, however, The Wonderful 101, Pikmin 4, and maybe ZombiU are the only games that really appeal to me.
Realistically, for Nintendo to win me over, I'd need them to give me something other than platformers and party games. A GREAT Zelda, a solid Metroid, and some new IPs where the primary input isn't jumping. I'm not saying FPS, but give me some variety. Oh, and RPGs, they could win me over with that, and I should add Project X to the list of games that interest me.
