2015 seems like a killer year for PS4 whereas the Wii U has Splatoon and Xenogears? No way Zelda comes out in 2015. Are there any other Nintendo games that are announced that I'm missing? I haven't had a Nintendo system since N64.
Yoshi's Wooly World and Kirby and the Rainbow Curse which both look great.
If you have to decide between a PS4 and a Wii U have though get the PS4. The Wii U is only great as a secondary system.
