I haven't frozen in a game yet, but have frozen between menus, and am having al lot more host migration, lost connection to host and freezing after getting bounced out of a game in progress.
And I'm curious if it's only BO2 too. (tutu?..lol) Only other game I have is Nintendoland, came with the WiiU. (Later edit- I just had a freeze in MiiVerse while responding to a post by Infinitlag, of all things. Had to unplug to get out)
its the U.
i freeze on BO2, Madden 13, Nintendo Land and Epic Mickey 2 too.
have not froze on Super Mario Brothers U.
My Wii U has frozen only when playing BO2 and if I've been using the browser and opened multiple pages with it.
The BO2 itself has frozen few times, I guess not the whole U since I could turn it off with the gamepad
My Wii U froze tons of times. Once with BO2, a few times during Mass Effect 3, once during Ac3 and twice during Zombi U. Like Convict7 everytime i could turn it off using the gamepad. Possibly a OS bug?
