Well.....Wasn't that bad, I mean its better than the last one they had in August, except for the 3rd party support. It really had me laughing on how low its getting. Next time they really need to show us how games like AC4, W_D, and Batman Origins will run on Wii U, show me that the Wii U version is worth a damn and I'll buy it instead of 'Oh yeah its coming to Wii U so buy it.'
