Bethesda/Gearbox point out why they don't support Wii U

[Cj2i3]

So essentially the Nintendo demographic doesn't suit the games that Gearbox and Bethesda publish/develop.
I mean if the demographic isn't there than perhaps the profitability isn't there either and that's why both companies are in business they aren't simply trying to break even.

I feel with Ubisoft they are supporting Nintendo's Wii U because they would like to try and get Nintendo fans accustomed to their games, so they are willing to take a loss early on and perhaps flip a profit later down the line.
