Speaking in a recent interview, the lead engineer for Assassin's Creed Mathieu Mazerolle has commented that Ubisoft as aiming for a very small threshold of 5% in terms of differences between the PS3 and Xbox 360 versions of Assassin's Creed. Mazerolle also noted that there is no problems with storage capacity constraints, their only concern/limitation is how to utilize the maximum performance of both processors to make the game as best as possible.

Quote:
Our goal is to ship the two versions of [Assassin’s Creed] to be within 5% or less of difference between each other. That doesn’t mean the PS3 is 5% “better” or “worse”, it’s really just an approximation and a statement that while the two versions are very similar, there will be (as there always is) small, hopefully inperceptible, differences between the two versions within a very small threshold.


Both machines are very complex and have very distinct strengths and weaknesses, so it’s almost impossible to quantify these sorts of comparisons - we just want to make the game as good as it can be on both platforms, and owners of both consoles will get the same experience from playing [Assassin’s Creed].

As far as adding extra content, it’s not really an issue: we have all the content we need for the game fitting on a DVD as it is, and the game wouldn’t necessarily be better by just by adding “stuff” on the disk: the biggest limitation for us isn’t disk space, it’s squeezing every last drop of performance out of the processors on both consoles to make the game as cool as possible on the screen!
