Here is a as of now COMPLETE look at what exactly you will be able to get for accessories for your xbox360 once it is released.

EDIT: Well sorry I should say ALL OFFICIAL XBOX 360 ACCESSORIES, I am sure there will be tons of nonofficial accessories however as of right now I have no clue what these products will be.

i hope they come out with some cooler face plates soon.

i like the wl controller

I believe $99 is a litlle steep for a wireless networking card for the 360. Maybe if it came with a router or something but it seems as though everything 360 has cnaged from the old pricing sceme. In the past if you wanted anything for the xbox, it was $30. Didn't seem to matter what it was. I believe that The rpicing for the console and accessories are starting to get a little unreasonable when thinking about the income of the average consumer and what he is able to afford on recreational expenses.

wireless controller is the best
