Not showing any footage of Watch_dogs Wii U or gamepad features isn't helping your own game to sell on the console. If you are going to invest in games, at least make a decent effort to show due cause for the fanbase to get excited for your software. It doesn't cost millions to make a trailer.
Anyway, this is business and they have every right to not invest in the Wii u ,if it doesn't make them money. The onis is on Nintendo right now to make the wii u a viable console to invest in.
