Looks like the Nokia 5800 will be part of the XpressMusic line of phones, which include luminaries like the 5310. At least according to the leak by the Chinese peeps, though why the new moniker "XpressMedia" wasn't used will be a question.

According to the source, The upcoming Nokia 5800 XpressMusic phone feature:

* A 640 x 360 (16:9) 3.2″ 16-million color display
* the Symbian S60 "5th Edition" OS
