They've probably looked at the Wii U install base, noticed that most Ninty fans aren't sim racer fans, looked at the work required to get it to the acceptable standard, and it perhaps just didn't add up.
It's a real shame for the game and Wii U owners, but that's business.
You should of handle the press release for this game, this is actually a sane logical thought that no one can argue.
oh please, they made the decision to port it to Wii U way earlier on, if they were going to make that decision, they should have done it waaaayyy earlier. But no, they thought that the Wii U was a great platform, talked up a big game, thought it would run great, and thought that Nintendo's install base and the lack of sim racers on there would make it sell well enough (see: the poll showing how much interest there was from Wii U owners). now they're going back on all that and screwing over the same people who supported the project in the first place with excuses that aren't even good. sure, it's business, but they're looking like pretty bad "businessman" right now and that reputation is going to stick with anyone who sees it for what it is. it has little to do with the Wii U's power or sales #'s or whatever and it has everything to do with making promises and not keeping them, IMO.
And just because you say "no one can argue" it doesn't mean that's actually true, you're just one person with one opinion -_- and you pretty much lose all credibility as soon as you say something like that can't be argued, because it certainly can be argued and it's just stupid to think it can't
