Toshiba sure does love their firmware updates. Their fourth update in as many months bumps the version number to a nice round 2.0, and promises TrueHD 5.1 support, allowing for full digital reproduction of studio mastered sound with 24-bit/96kHz discrete channels. As our friends at HD Beat astutely point out, it ain't no Blu-ray support, but it's a nice one-up on the competition all the same. No word on when exactly this will drop today, but we wouldn't stray far from the remote if we were you and had an intense craving for yummy TrueHD and expansive version numbers.
