Ubisoft has officially confirmed, via their community forums, that a patch for Rainbow Six: Vegas 2 is in development.

So far, all we know is that the patch will fix the Private First Class achievement. The problem with the achievement is that those who have a save file from the previous game get an XP boost which puts them above the Private First Class rank thus making the achievement impossible to obtain. Ubisoft also let us know that they are looking into the connection issues present on the PS3 version of the game and a fix concerning the issue will be included in the patch.

There is currently no release date announced for the patch.
