It's not so much bandwidth that they are trying to reduce (because I doubt that bandwidth for the stated games is that high). The issue is "shelf space". If a consumer has to scroll through.......10 bad games they won't buy, to find 1 game they have a good chance to buy, it means that your list is in-effective, and is choking good games out from sales. It's almost like a knee-jerk-esque reaction to the MetaNet rant a few months ago about total crap on XBLA.
Ultimately, MS needs to tier the XBLA games - New games first in 1 blade. Highly rated games in the next. Console/Arcade classics in the next. All games in the last blade. That way a consumer can just go through the good ones, rather than just do an alphabetical crapfest.
Back from the dead, I'm afraid.
