Microsoft, it appears, is driving third-parties to develop new game sections for later download.

It appears that some more cynical gamers out there had decided that Microsoft was in fact simply paying developers to cut sections from completed games for later delivery.

"The DLC that we're making for Microsoft is especially made. It's not part of the main game that we saved", he is quoted as telling videogamer.com.
