How much do you want to play MK8 and SSB? If you cant wait and you need those games then i would suggest that you purchase the wii u when MK8 launches. If you dont mind waiting and your patient enough, then wait....however good games such as X and bayonetta 2 are also out this year (correct me if im wrong) which will most definitely keep your interest.
In my opinion and what i am doing is waiting. X looks great and im sure SSB will be too but for me they are only 2 games i really really want (kinda like you) Thus they dont warrant the price or time i must waste on the console specially considering i like what im seeing from the competition alot more. I will purchase a Wii u when the next big Zelda game releases and by then i hope it will be cheaper and will have a good back catalog....something i can never catch up on these days :(
The perfect price for me is $200 for Wii u
