This makes me wonder if it's just poor software design or hardware.
The Halo games and Mass Effect are high profile exclusives, each with enormous development budgets, Halo 2, Mass Effect and Halo 3 are not some early XBox 360 games, the design is easier to get good results early on as it has more in common with traditional solutions especially with the PC, they had very long development times, the XBox 360 has been on the market for two years when Halo 3 and Mass Effect were released.
Unless you want think the game engine devs are incompetent to get the most out of the XBox 360, I think you can come to a conclusion yourself.
