According to the JP marketing materials, they are using a newly developed LSI circuit, and the latency
is down to less than 1 frame (they have an asterisk that it depends on the input signal, I'm assuming
that's to cover their butt for interlaced signals). This seems to be a big improvement from the earlier models. Still only 720P though.
First time I might be interested in getting a HMZ. Was not interested before due to lag.
