If it's got an HDMI port and it's supported by a big name brand then it's going to be updated. There's probably an upgrade for you out already, have you checked since you got your TV?
correct me if Im wrong but I use to be into the modding scene for xbox original. I thought I seen people formatting PC hard drives to work with 360. As far as I know 360 is still in the development of modchips working correctly. I myself have the firmware flashed and am perfectly fine with burning the games atm. Especially is cool to modify the games and then burn them to dvds and run them. Kinda silly on Microsoft's part that they are letting this go since it upraises many problems over xbox live with modified game content.
