On a recent podcast with Major Nelson Xbox Live's director of product management Aaron Greenberg let out and re-confirmed that Xbox Live will be cleaning out all they under performing Xbox Live Arcade titles. He went on to say the already stated: Games that have been on XBLA at least 6 months, have an average rating of less than 65 percent and have a conversion rate of less than 6 percent will be removed from the listings. Microsoft counts a conversion every time someone downloads the trial version of a game and then follows it up with a purchase of the full version.

He went on to say that people who have already purchased a de-listed game will still be able to play it and have online and leaderboard features as well as be able to re-download it from the marketplace. Everyone else will just see un-purchased, de-listed titles disappear from the marketplace.

Greenberg also mentions a few more things like:

Total Xbox Live games: About 130
Average daily downloads: About 1 million
New XBLA game file size cap: 350 MB
Percent of first-week U.S. GTA IV purchases for Xbox 360: 65
Number of items on Xbox Live: About 17,000
Number of items on PlayStation Store: About 600

It was also mentioned that although some games are below 65 and 6 percent or w/e, the popular ones will remain available. Frogger, pacman, and texas hold em will most likely stay.

they should have a category for these games. so they are never really gone, as an option to us.
