I think you'll be just as frustrated with WiiU once come April and you've finished all the already announced games. 3rd party support looks like it will be poor based on announced WiiU titles past launch (and sales of current 3rd party titles outside of ZombiU) and Nintendo cannot get games out on a regular basis for long to save their lives (or systems) as seen time and again.
Save the frustration and get a 360/PS3 and you'll have enough games right off the bat to last you for years (cheap too) and that'll include half of WiiU's library.
Once Zelda, 3D Mario, Smash Bros, Kart U comes out, then get a WiiU.
