Sony Ericsson Dual Core Phone Call Duo

Sony Ericsson haven't release a dual core yet but instead they release the Xperia Play which is I must say a great phone, it feels great combining the game factor from the psp and  integrate it with Android system which make the Xperia Play. Enough about the Xperia Play, now is this unknown phone, whether it's a mock up or real, source says this might be how Sony Ericsson first dual core phone look like as how the screen is stretch to the edge of the screen giving the phone a strong processor which is the dual core to power this phone up with its magnificent big giant screen. It;s using the Xperia interface so maybe a new family to the Xperia family?
