THQ has confirmed an August release date for Darksiders II, which is just a ways back from the planned June release. THQ has made sure people know that the delay has nothing to do with the Wii U by putting together a FAQ sheet.

Q.) Has the date been pushed back to tie in with Nintendo’s WiiU™ launch?
A.) The date was shifted to ensure we meet the high quality threshold that we are committed to achieving. It has nothing to do with any other platform releases.
With that said, let's hope we see the Wii U version at E3!
