It's really Steroscopy
I can't be doing with it all, I really can't.
Its really hard to justify HD, let alone 3D.
Pubs are full of Giant 625 line screens showing footie to halfwits. I've never once heard a knuckle-dragger complain that there weren't enough pixels on that.
The more pixels there are the worse the compression artifacts get. You know those amazing shots of the start of the London Marathon? or of flocks of barnacle geese all changing direction at once? I've seen those block-and-freeze on ordinary dtv. 3D must have twice the pixels. No thanks.
