As usual poor old NZ is behind again - Panasonic in Australia has released DMR-BWT820 and in April will be releasing the DMR-BWT835 http://www.panasonic.com.au/Products/DVD+and+Blu-ray/Blu-ray+-+players+and+recorders/DMR-BWT835/Overview The only thing that is really missing is a browser and an iDevice or bluetooth keyboard connectivity..
Probably not really very far behind.
The BWT720 has been around for 2 years in May. The only difference I can see with the BWT820 is a larger HDD and maybe a couple of new functions.
We must be due for release of new models very soon.
