lol.. wrong.. 1440 ??? where the hell did you hear this from ? best buy? IF they jump to a new generation in the next year or so it would be a cinema hd which i think is 4096x2160 ( 99% doubtful , just due to BR being released , new LED's , the world is just now set up for 1080P! .. Thats like releasing ps4 one year after ps3 is released.. To much investment and not enough time for profit)
BUT .. thwe next "generation of HD , will IMO be in 10-15 years and its called Ultra HD, with a 7680 × 4320 resolution.. Now that is going to be beyond what anyone could imagine..
Ill try to find an example , but try to search the 2 in comparison , and compare a 1080p image or movie clip, to a 4320 resolution.. its unreal how 1080p looks like static in comparison
