I'd get the PC version of most shooters (and 3rd party games in general) before any of its console versions, so no I wouldn't.

how many signatures must be collected?

Truthfully I think it would sell enough to cover port costs. However at this point it would end up late like watch dogs and nobody would care about it by then and it would fail and activision/ubisoft will wonder why.

Not really, nintendo games, both first and third party, are best when they are single player experiences.

If wii u could handle a persistent always online universe game, then it should be a shoe in for wii u.

But until they can prove they can handle a heavy online game, it wont come to wii u (yet)

Yes, as long as I don't have another system at that point.

10 minutes ago the goal was 1500, but it bumped up to 2500 after passing that.

I'd buy a Wii U version if it had Wiimote controls and if there wouldn't be a pc version
But I want a pc version with mouse controls.

If someone has a current generation console other than the Wii U I don't see why they would want this game on their Wii U instead of PS4/X1. It would have better graphics, more players online and from what I've heard Nintendo's online network isn't as good as PSN or XBL.

The game never caught my interest, but if it did release on the Wii U, I would consider it since Bungie might do something interesting with the gamepad.

I guess not. I would probably buy the PS4 version (exclusive content / better visuals / online).
