Well, it looks like the rumors are true – Splinter Cell: Double Agent's release date has been pushed back. The game was supposed to be released this March, but now it will be hitting stores in September.
The official company line is:
"Ubisoft is extending the launch of Tom Clancy's Splinter Cell Double Agent in order to deliver the highest quality gaming experience. The additional development time will allow for a simultaneous worldwide launch on all platforms and will allow Ubisoft's development teams to push the technical boundaries on each platform."
Ubisoft has yet to let anyone down with any of their Splinter Cell games, so it's a safe bet that this delay will result in the game being highly-polished when it is released.
