Did anybody else really enjoy the cell shaded Prince of Persia? I thought it was a very calming game to sit down and run through. Ending was fun as well. If they were going to do a sequel I think we would have seen it by now. I'm always disappointed when a game takes a risk and it doesn't succeed. The next PoP will probably resemble Assassins Creed.
Weird that you bring this up today, as Ubisoft announced yesterday that the series is on hiatus. http://www.ign.com/articles/2013/01/29/prince-of-persia-franchise-paused
Doesn't seem like they're abandoning it, and I think this may be because it was running parallel with Assassin's Creed and had relatively similar gameplay styles on the surface.
