Oh my. Looks like Gracenote has unintentionally stolen Sony Ericsson's thunder by outing their phones before SE's "next big thing" later today. According to their press release, Gracenote's mobile music service will be embedded on the "new Walkman models W910, W960 and the K850 Cyber-shot." Of course, there's still some mystery as we don't yet know which internal codename -- Sofia, Maria/Mooi, Shinobu, or possibly others -- matches up with those new product numbers. As to Gracenote, well they'll provide search and discovery, song ID and playlisting, and allow users to transfer music between home libraries, on-line music stores, and their new SE phones. But really, it's only the phones you're interested in right?
Update: Well, well now BelgiqueMobile seems to have the leaked pics and specs: 5 megapixel cybershot K850i with HSDPA/EDGE; W910 HSDPA Walkman 3.0 slider with 2 megapixel camera; W960 Walkman Touch player with UIQ 3.1, WiFi, and 3.2 megapixel camera. There's more, but not more if you knowwhutamean?
