today I picked up a TC-P55UT50 at costco... there were two available in boxes, I choose the one with a higher serial number and noticed the PRINTED AND GLUED label on the box had a "-2" at the end of the model info. ie: TC-P55UT50-2
the other box with a lower serial number did not. both boxes are designated as TC-P55UT50 (only the printed and glued label on the one has the -2)
anybody know what the -2 designates?
