It isn't as bad as the title suggests but yes, unfortunately, the release date for the newest game in the Prince of Persia franchise 'The Forgotten Sands' has slipped by just a few days.
The game was scheduled for release on May 18 on 360, PS3, Wii, PSP, and DS, now however it will release on May 21, so an extra three days to wait.
The PC version is unaffected however since its release date is still schduled for June.
Why is it delayed? Ubisoft haven't said.
