hd is about 17yo. since the transition. from standard def. every manufacturer. producer. distributor. etal want to make money from their 4k investment. it'll take awhile before we see 8k. at least 10yrs. i'd be suprised if 8k was mainstream by 2025

btw. 16k and 32k have already tested successfully

the industry want to make money every step. and they will. watch manufacturers phase out high def tvs by 2017. they'll force everyone to buy 4k. want a tv? you'll buy 4k/uhd +hdr or none at all matey...
