In a recent interview with Jade Raymond , producer of the highly anticipated Assassins Creed for PS3 and the 360 was asked about the possibility of a Wii version. Raymond had this to say; It would be possible, if we completely changed the gameplay, just like the DS-version. But it wouldn’t be the same experience. Raymond was also stated saying that, If the Wii had the same power level of the 360 and PS3 the team would have seriously considered a Wii port. The DS version unfortunately is not being handled by the same team but heres hoping that the portable version will live up to the same hype as the 360/PS3 game.
