I am so sick of aspect ratio's and all the little improvements. I swear they do it just to make a disposable tv. Lets see you have 4:3, 16:9, 16:10 (for computer monitors). Cold cathod (could have been led from the start), rear projection, dlp (which no one makes anymore so wont be able to find bulbs) 120hz., 60hz, they want 240hz for 3d, which is another crap technology. Not to mention they introduced HDMI late. So I paid 2500 for my first hd tv, with no hdmi.
I think that when they pushed hd through all the tv companies saw a way to do incremental updates to rape the consumer out of a bunch of money.
