People say this because they want to see how the IPs play on superior hardware. Not on a console where the company purposely eliminates this possibility.
i'd like to see their hardware be better but i say this as a Wii U owner. not some guy sitting on the sidelines not supporting the company and not buying their products who would if i didn't have to pay the barrier or entry ($350 + $199 Wii U Deluxe / 3DS) to be able to access their library of games.
i'm far from rich i just came to realize the thinking i myself am even guilty of of people who backwards rationalize why they don't buy shyt they can't really afford anyway even though deep down they really want it.
what i'm saying is this if Mario and Zelda came out on the 360 and PS3 and you'd actually buy it then you wanna play Nintendo games and really have no business shytting on them or their consoles.
