In an email to a Republic fansite on Friday, Elixir's Demis Hassabis confirmed that "the game is done and the Gold Master candidate submitted (in 6 languages!)."
Republic has been the subject of much speculation after it slipped from its June release date, but it now seems set to come out later this year.
"It's now up to Eidos how fast they want to turn the manufacturing and distribution process around," according to Hassabis. "It's possible to do this turnaround in two weeks but they've decided to delay that to September to ensure a simultaneous worldwide release."
Of course this is not the official Eidos 'gold' announcement, but it's good news for those looking forward to Republic, which has received fairly positive early reviews in PC games mags in the UK.
