Pier Solar HD on Wii u being held up by Microsoft submission process

"We're starting the submission process for PSHD. Valve already approved it for release on Steam so that's done and done. We may contact some of you who subscribed to beta test to test the game on Steam using a beta key. Stay tuned. Microsoft already evaluated Pier Solar as well but we failed some internal requirements on the certification and we're correcting them for the next submission. This also impacts Wii U and PlayStation(s) submissions since we want to send it as clean as possible so that we don't get another failed certification. " – Joystiq
