RUMOR-360 Fall Dashboard Update Leaked « The Xbox Domain
I dont remember the last update for the dashboard that shipped without an internal leak. Again the info on what will be floating around on your 360 has been revealed and I can’t really call B/S on this one. I dont exactly know how the all these new blades will work, such as the Xbox Live Arcade Blade and a Flash Gaming section(yes weird). The list is after the break, but the major highlight is XVID support. After months (years) of waiting we finally dont need to transcode our home movies.
