I'm hoping it's dead in a ditch somewhere with Randy Pitchford burrying it, before getting caught by the local sherif, and then he kills the sherif and is a man now hunted by the law for tripple homicide, murder of the sherif, murder of a game, and murder of a franchise (but let's face it there are MULTIPLE suspects for that one).
However this thread is more of a theoroy page on what happened to the Wii U version.
My theory is that the Wii U version wasn't even made to begin with. The fiasco at Gearbox probably only just managed to get the PC and PS360 versions out on time. I reckon they hadn't even started on the Wii U version because Randy Pitchford is a god damn lying son of a ************ so with a game that didn't even begin development, and the fact that everyone knows the game SUCKS WRETCHED MONKEY TESTICALS Sega dropped the Wii U version (we dodged a bullet people! probably one of the only times NOT having a a game on your console goes for plus points in getting one) as no-one would buy it.
That's my theory on what's happened. The only way I see this getting resolved is if they basically build the game again from the ground up, with a new plot and with a different development company who can be trusted not to spend dev money on other projects.
