We first saw the retail edition of Toshiba's 3840x2160 resolution autostereoscopic (no glasses) 3DTV when it was announced in Europe at IFA
last month, and now it has debuted in Japan during CEATEC. This time the company dropped a few more details, revealing that in lenticular 3D mode it's limited to an effective resolution of 1280x720, and showed off the face tracking that automatically optimizes the experience for up to nine simultaneous viewers depending on where they're sitting. Also mentioned were an optional THD-MBA1 input adapter due in 2012 and that 4K-res streaming IPTV is currently being tested. The Regza 55X3 will be priced comparably to its $10K~ Euro-spec counterpart when it arrives in December, but there's still no word on when it will ship in the US. Check out a few pictures of the presentation in the gallery below.
