It's very logical to assume that Halo has lost a bit of steam, though. The market wasn't near as crowded when Halo was at it's peak. No doubt Reach and 4 changes pushed some of the community away, but other games also can be attributed to pulling some people away. Just look at the competitive multiplayer (and even co-op multiplayer) game scene nowadays compared to Halo 2 in its prime, completely different and much, much more crowded.
It's a combination of many more options and series changes that's put Halo where it is today.
The crowded market is a good point but i really think the quality after Halo 3 made a lot of people leave.
