A new phone, the Yendo, has been announced, which is pretty much like the X10 mini but with a good Walkman thrown in, has been announced, but I haven't seen anything about something to add on to the X10 or its variants. I do wish it would happen, though. The music player on the X10 is nothing like as good as on my old Sony Ericsson (?)W580i, other than the album art facility.
Let's hope it's both possible and actually done...
