The final code for software implementation will be given to the receiver manufacturers on January the 1st. The manufacturers would then need some time to impliment this in relation to their hardware configurations. The final implementations should start to become available shortly after this, but you'll probably find that the update will be rolled out gradually rather than all applicable models getting ot at once. D&M have indicated that the flagship models will get the update first. There's already a DEnon AVRX7200WA in the UK running a beta version of DTS:X.
