The Z1 or the TC-P54Z1 has been spotted in a San Jose Magnolia store although it hasn’t been officially announced by Panasonic yet. The Z1 is an impressive 54-inch wireless HDTV which is only one-inch thick and, most importantly is expected to arrive soon enough. What do you think, are you ready for a new Plasma in your life? Make sure you have those $6,000 needed to purchase your Z1 HDTV.
