Nope, 3view isn't there - hasn't been released yet as far as I know.
You've got the Sagemcom RT190-320, the Digital Stream DHR8205U, the Technika Smartbox 8320 and the aforementioned Philips HDT8520.
Have just heard rumour the update isn't due for another 2 weeks, but there's been so many rumours on the HDT8520, I'm not going to pay it much mind. Philips have got till the 3view and Humax boxes have been out a few days and I've had a chance to see them in action. If they're better, it'll be swapped subject to JL's customer service - here's hoping one of them pulls through!
