User blog comment:Master Sima Yi/Assassin's Creed III in 2011?/@comment-2122408-20110411145441
Great find, this actually shows that there's a VERY strong possibility that ACIII will be the "packaged" release.
One of the reasons for this is he stopped working at Ubisoft Montreal in November 2010, meaning he was doing texturing work on the game before Brotherhood was even released. This would mean that the game has actually been in development for quite some time as texturing is also one of the later stages of game development.
Therefore, we don't need to worry about not enough time being spent on the game since it's been in dev. for so long.
Plus, (as much as I love Brotherhood, it's true) Brotherhood probably took far less resources/time to make, (minus the multiplayer) as it is essentially Assassin's Creed 2 with less areas and a few new gameplay additions, giving them time to start dev. on the third game.
