From August 11th the Xbox Live dashboard will be looking different again as it gets Games on Demand, Netflix party support and the Avatar Marketplace.
Confirmed as amongst the first full Xbox 360 games to be offered via digital download are BioWare's Mass Effect, 2K Boston's BioShock and Ubisoft's Assassin's Creed. No Last.fm.
Also Traveller's Tales' LEGO Star Wars: The Complete Saga and SEGA's Sonic the Hedgehog will be on the new Games on Demand service. Facebook and Twitter integration, along with full 1080p streaming video, will not be present in the major update.
