you give them too much credit. I doubt very much any manufacturer is planning 2 or 3 moves ahead at this point...
it's different for the sake of different. if you can't fix blacks, or uniformity, or motion, or viewing angle... and you can't afford to reduce pricing... but you're already in debt so you need to sell more units...
basically they NEED something to make new TV's 'better' than the old ones. the only thing they were capable of was doing the curve thing and hoping it was different enough that ppl not only upgraded their main display, but maybe even a second of third as well.
like when widescreen TV's came out, ppl were a lot more likely to buying multiple TV's within a year. in one year I bought 3 32" 16:9 TV's. they finally hit a price I felt comfortable paying, and I'd wanted to get rid of the remaining 4:3 displays, so, bought a few. I would never have done that just for a higher resolution, or a better quality, but I did it for the new form.
unfortunately, for them, I don't think ppl will care that much for the curve at best. seems like the most positive comments about it are things like, "it's subtle, so I hardly notice it most of the time". very few ppl are actually considering it a huge selling factor, and want to ditch the flat screens all over their home.
now, why is LG making their oled curved? peer pressure I guess. and that's really unfortunate. not only would I pay more for an oled over an lcd, but I'd also pay more for a flat screen over a curved one. so in the end, I would absolutely consider paying double for a flat oled, instead of a curved lcd, a great option/value.
I was ready to drop over 3k on a 60" zt60 last year, if oled is still 3grand for a 55" when I need a new tv, it'll be the obvious choice for me
