Despite this knowledge, people buy what's available in stores today, clearly because they either have a need or a desire for something now - not months or years down the track.
Technology companies also have to be careful about what's coming from their competitors, and have to try and create products that will remain feature and price competitive - no matter what shiny new feature a competitor releases.
Thus, at CES this year, came reports of all kinds of advanced televisions able to run apps and access the Internet, TVs with super thin profiles, TVs that respond to motion controls and your voice, TVs running Android Ice Cream Sandwich and Google TV, TVs running anything and everything - but an Apple OS.
Clearly, all these TV manufacturers are doing is placing ever more advanced computers into what was once merely a 'dumb' screen.
These TV computers are getting smarter, faster, more capable - and are paired with screens of ever higher definition.
And of course with Siri having done its bit to kick off the voice interface revolution, despite all the work by many that has gone on before, your next TV may well be one that responds to your hand movements and your voice by itself, just as an Xbox 360 and Kinect can deliver to any modern TV right now.
One report comes from Fairfax Media's Asher Moses, who was sent by Samsung to CES as one of its guests, and who reported on Samsung's ambitions to dominate in TV and fight any Apple TV initiative tooth and nail.
Australian Samsung executive Phil Newton explained that Samsung wasn't worried about any future Apple TV, was well positioned as a complete manufacturer of all parts of its TV chain, had plenty of its own innovations and already had TVs planned out to 2014 - with his exact quotes available to read at the link above.
