I read the OP again and I think I could answer better this time. Since you're not going to wait until E3, which would be better, at the moment the Wii U obviously has the best exclusives. The XBO has a better selection of games compared to the PS4 at the moment as well. However, I feel that by the end of the generation the PS4 will have a better and wider selection of games compared to the XBO. The XBO will get big Japanese games like FFXV and KHIII, but I doubt it'll get support from the smaller Japanese devs.
So pretty much if you can't live without the Nintendo staples like Mario and Zelda, get the Wii U. If you can't live without Halo and GOW, get the XBO. If those two conditions don't apply get the PS4, because in my opinion it will have the largest and maybe most diverse library by the end of the generation.
