Flamingcheeze writes "According to a Reuters article: 'Microsoft Corp. is planning a number of new features for its Xbox Live online gaming service this year, including... something called 'title-managed online storage,' a way for game players to store and share data via Microsoft's network.' The piece goes on to note, without directly drawing a link: 'speculation within the industry that Microsoft may not include a hard drive in the next version of the Xbox console, in favor of network-based storage that would reduce the console's physical size and cost', as recently discussed on Slashdot Games."
The article also mentions possible "indications... that Xbox Live would eventually allow players to leave each other brief voice messages"
, and a story at GameSpot
has further, albeit brief details on this 'Tsunami' upgrade.
