Definitely some strange, noticeable absence of new HDD DVD Recorders from Sony these days in the North American market.
Sony/UK has had a next generation HDD DVD Recorder for sale for six months already, beyond the last model that Sony had for sale over here. The last model that Sony had for sale here, the HX-715, has been discontinued with no announced replacement.
Sony/Japan, is at least two, if not three generations ahead on HDD equipped DVD Recorder models then what was sold over here, in the North American market. And they regularly come out with new models all the time over in Japan.
And these are not HD models, but just SD recorders. So how much more trouble would it be to just "Americanize" them since they are more or less designed already?
