Thanks for the advice on buying and all, even if that's not this thread is about :P.
I'm just pondering where tv will go eventually. In the beginnig we had pictures without realtime sound. Then came tv with that realtime application. the next great step was giving colours to the picture. Further down the line we changed the picture from analog tapes into data processed by computers etc. What next? Because outside of increasing picture resolution, there's not much more to do, is there?
Or maybe i'm just short sighted :).
As to when HD will become a standard, i must say that america isn't the one to call the shots. I'd put my money on the far east. china, india, japan. Most of the technology comes from there, so i would guess that what they say, goes.
