What more possibly could they offer consumers?

As I sit back and think what might be coming to the consumer AV market in the near future, I can only think that there will likely be more integration between the internet and home entertainment media - maybe more access to home automation from the intenet, from cell phones, etc. So, what is posibly left for the AV industry to suprise us with here in the next ten or so years from now? I mean, sure, they'll likely be offering higher resolution video potentially, upscaling to 4k, etc. But really. How important is that to the average consumer who will have nothing more than a 55" flat pannel tv? I think it's not a big deal accross the board. And certainly the HD video disc is gunna go away, and all will stream over the net, it appears. (surely, they won't make a killing selling 4k HD discs, cause discs sales are slowing down) Only those who do UBER LARGE displays, projection systems, etc, will really get any benefit here...the sucess of which is no more likely than the "mass-less" exodus from people buying 720p displays going up to 1080p flat screens, or DVD discs to BluRays, and so on?
Face it. Who's gunna swap out there 1080p 50" LCD tv for the same size in 4k? I would submit about as many as who did the same in upgrading from 2D HD tv's to switch to 3D LED TVs!!! -Yeah, exactly.
Beyond the obvious melding of streaming videos and internet through your TV/Media center, and all TV being integrated with the web, what other supprises could be coming to the consumer in the Audio/Video arena?
I could possibly immagine Holographic images hovering in my room, with virtual surround froma single sound source, possibly. But maybe higher end sound procesing or even more surround speakers to have to place around the house? Can't even get my fiance to go with more than the two that are built into our TV!!!...let alone 9.2 or 11.2, etc!
Let's face it, we are more intregued by how smart our phones are, and that segment seams to be ever evolving. I mean it was like, what, less than 3 years ago that the Motorola Razor was the hottest selling phone on the market?! - YYYYYEEIIKES!!!
I just can't envision anything that'll be coming our way for AV, anytime soon, that will be a major game changer, or the "next big must-have-thing!" And unless the gaming industry is picked up by 40-somethings and the aging, how impactful is going to be wrap-around video gaming screen setups in your closet?
I'm visionless for what could be coming at the present, personally. All i can see for the next decade is my 7.1 channel receiver (I'm barely using 5.1 channels of it, and mostly 2 ch stereo) with my Ipod connected, my Netflix enabled BluRay player for HD and streaming, and my 1080p JVC projector and light rejecting projector screen. Beyond this, I can't envision much else
