New 3D glasses (TY-ER3D4MU, $65)

Like all plasmas, the ST50 uses active 3D technology. New for this year, Panasonic's active 3D glasses support the universal standard. In practical terms that means other companies' glasses that also support the standard should work with this Panasonic, and also that no 2011 or earlier Panasonic glasses will work with this TV. At $65 each, the new Panasonic 2012 3D glasses actually cost twice to three times as much as Samsung's cheap models (the $25 SSG-3050GB and $20 SSG-4100GB), so I wouldn't be surprised if that price fell soon. All universal glasses use the Bluetooth standard; check out the CES writeup for more.
