With all due respect ... this is completely incorrect.
Version 1.07 firmware only addresses PAL/SECAM video color balancing.
Anything more is incorrect rumor which, if tracked back (via the AVS Forum) will be found to be nothing more than hopes/wish list that was misunderstood but posters.
Here is the quote directly from Japan:
"The official ( and real) comment on the firmware 1.07 is as follows.
Serial number for firmware 1.07 is 514**** or after.
As we informed the difference between 1.05 and 1.07 is only PAL/SECAM video color balance, so we do not take any special action for this change."
If it would help to finally kill this rumor ... I'd be glad to produce the email itself.
