Sony Ericsson PlayStation Phone to be called 'Xperia Play'?

We've been hoodwinked by trademark filing and domain registrations before (cough, BlackPad and SurfBook) so we wouldn't say this is anywhere near definite, but we just caught wind of a Sony Ericsson EU trademark registration for "Xperia Play," and SE PR firm Jung Relations has registered a variety of Xperia Play domain names, including, .net, and .org. Yes, that certainly sounds like a promising name for the PlayStation Phone (although not quite as promising as, you know, "PlayStation Phone,") but honestly we wouldn't bet on anything at this point. We've got a feeling we'll either find out either at CES or at MWC in February -- hold on tight.

Update: Turns out SE also registered Xperia Arc, Xperia Duo, and Xperia Neo, so now our interest is definitely piqued. And our hopes are totally shatter-able.
