I think the release of Mario Kart and Smash Bros. alone, along with the possibility of them being able to finish and release Zelda U in late 2014, will raise the Wii U's hardware sales significantly. Also, just having a lot more games available for the console in general, such as Bayonetta 2, X, etc., would really help.
And when the FUCK is Square going to get off their asses and finally bring DQX to NA? You'd think they would have done it by now, especially considering that online/mmo type games are far more popular in the west than they are in Japan. DQ is a million selling franchise that has now sold even close to a million copies for DQX in Japan. It's been plenty of time now for them to localize it, set up NA servers, etc. So just fuckin' get it done already. Square needs to make money off of that game, and Wii U could absolutely use a solid online excursive like DQX in the western markets.
