i don't know if an add-on would work on a Wii U to improve hardware. if it is a totally new 'new' Wii U console yes the previous buyers of Wii U would real be pissed off.

as I'm not familiar on how they built Wii U so it is hard to know on how to make it easy portable the Wii U to accept 3rd party games under x86 architecture. Madden, Fifa and NBA alone can add a ton of fans buying the console - nintendo + 3rd party sports is already a sell in. add GTA, COD, BF, Diablo then your talking. it is not even a competition if Nintendo has the 3rd party titles too... it is not daydreaming (for the other console fans) but it is true. if Wii U is at par with PS4 and X1, 3rd party titles are the same + Nintendo exclusives. it is really game over. I think that is why a lot of Nintendo haters are leaning to. they wanted the competition to die because they already know if it happens. they'll lose the gamers on their platform.

i think Bayonetta is not really the one genre for Japan. but the sales would be better in Europe and NOA>

it is the sad truth. Nintendo is the one to blame. is it too late? if it is an inferior hardware, would Nintendo add hardware to make Wii U atleast par with PS4 and X1? so that most common games would be ported easily to Wii U?

i love their games but like what most have said, the 3rd party/multiplat games are always inferior to other gen ports. so it is really hard to value a $60 inferior game and several gamers would own another console or PC to justify their buy on that game.
