The spring Xbox Live update may be just around the corner, and ready to introduce support for "motion sensor devices".

That's according to a list of features leaked to Kotaku that originated from a supposed internal source at Microsoft.

There's no date attached to the leaked spring feature list; last year it went up on 6th June and we'd heard about it as early as April.

Most of the 80 bullet-point tweaks are rather trivial, but a couple caught our eye: "Option to donate Microsoft Points to anybody with a Windows Live ID," and, "Calibration options for motion sensor devices."

The first because we are greedy and the latter because, er, what is this "motion sensor", eh? It could, of course, be some sort of Live Vision support, and not necessarily the bizarre Wii remote-alike device blueprints that popped up on the Internet in April.

"We don't comment on rumour and speculation, and we have not announced anything regarding Xbox LIVE updates," was all a Microsoft spokesperson had to offer.
