If these are the best games on the Wii U right now I'm glad I haven't bought one. Mario Bros and ZombiU I'd be interested in. But the rest either don't interest me (nintendo land) or I can grab on a console I already own (batman arkham city / Darksiders 2.)
I'll admit that the WiiU has a strong launch lineup (when compared to previous consoles) but it hasn't wowed me. I mean lets face it, half the lineup are ports from the current gen. All they're selling is a PS3 / 360 gen console with a tablet controller on it.
I know the console is more powerful, but I just don't see that power being used by third parties. Why rewrite their engines and develop for the WiiU when that will be dwarfed in power in 2013 (possibly 2014) when they can keep making games for cheaper on the PS3 / 360 with its larger market share, and then port over to Wii U.
Until devs start to actually make use of the hardware in the WiiU fully, I just don't see any point getting it when I have my current consoles.
