Ubisoft has confirmed the Ghost Recon: Future Soldier release date as March 6 2012 in the US.
While nothing's been confirmed for the UK yet, it wouldn't be unreasonable to pencil in Ghost Recon for the EU on March 9.
The publisher put forward a March release for Future Soldier way back in June but have only just released a specific date.
Have a look at the Ghost Recon: Future Soldier multiplayer gameplay trailer that came out of GamesCom earlier this year if you haven't already.
There's a Ghost Recon: Future Soldier beta set for January as well.
