Our ground PONG-snorting buddies over at Kotaku have gotten their hands on a potentially legitimate list of new functions coming with the annual Xbox 360 Spring Update. In the list we see more confirmation of the Newton motion controller, as well as hints at a news/weather service, more hard drive game data caching and four-person video conferencing. Microsoft has denied the list by saying, "We don't comment on rumors or speculation, but what we can tell you is we've never seen this list before." Honest denial or tricky wordplay? You can decide for yourself with the list after the jump.
