It's really an hard choice. I'm considering to buy a Wii U cause all the great games it has + the hardware seem awesome. (Gamepad, I can use my old Wiimotes etc...)
And I really don't know if I'm going to buy both. If I buy the 3DS first I will maybe not buy a Wii U for this game and if I did I'm scared that I don't enjoy the game cause of the same feeling (Like when I've bought Soulsilver and Heartgold, loved Soulsilver, never finished Heartgold)
But at the same time I don't know if I will resist to see all those Smash Bros 3DS copies in my store. ;_;
My favorite Pokemon game (And my favorite game of all time) is Pokemon Mystery Dungeons: Explorers of Sky. It's an underrated masterpiece that beat in my opinion some of the most acclaimed RPG games like Chrono Trigger and Final Fantasy 6.
