Tomb Raider: Anniversary Downloadable?

With Tomb Raider: Legend's release it was the first commercially successful game in the series for a long time. This was due majorly to the Xbox 360 version that topped charts. Now it's surprising to see that not only is Tomb Raider: Anniversary missing a 360 release, there seems to be no next-gen release at all. However, the ESRB website lists both the current release on PS2, PSP and Games for Windows but also has each of the levels seperately and available for 360.

The ESRB does not usually do this when reviewing a game, they would look at the whole package and give it a rating. This leads many to believe that the game is actually sold broken up, and what better platform to sell an episodic game than the Xbox 360? Whether it's testing grounds for future episodic releases on the system, or just a way to avoid justifying $69.99 for a remake of an old game it looks like the 360 will be getting the game, just wait for the press release now.
