New large-screened Nokia Lumia leaked?

(Image removed at Microsoft’s request)

MyNokiaBlog has been sent the above picture, which is a prototype Windows Phone 8 handset with a rather large screen. The device appears somewhat blocky but with a rounded bottom.

The presence of Family Room confirms it is a Windows Phone 8, not 7.8 handset. No other specs are available.

Given the absence of specs, what do our readers think of the design? Let us know below.

Update: Another picture (via BGR) shows the device, which is code-named Juggernaut Semaphone, has a WVGA screen, which marks is as a lower-end unit, rather than a new flagship. (Image removed on request by Microsoft).
