This year a few of the trends are:
-4K televisions. Everyone is showing off 70"+ 4K televisions. 1080p x 4 = 4K. Sony is promising to actually distribute something in 4K to watch.
-Google TV boxes and tv sets with the operating system built in. A number of new ones. Maybe this year Google will start to take their own platform seriously
-Dish is debuting a new Hopper DVR (that thing with the annoying tv commercials) that has a Slingbox built into it. The Hopper/Joey set up is actually awesome. If I were interested in satellite this would be my first choice. If you have an ipad you can sync it to take recordings offline, for a plane trip or car ride with limited high speed connections.
-5G. Urgh
-Samsung's new bezel/base stand.

-more electronics in vehicles. GM wants you to develop apps for their cars. Angry Birds on the Parkway?
-quad core processors in tvs
-more point and shoot cameras with interchangeable lenses and wifi connections.
-AMD is showing off more advanced x86 (processors for Windows based computers) with the graphics and other parts of the system on the chip itself. These will find themselves in lots of Windows 8 tablets and Ultrabook style laptops. Intel is showing off Bay Trail, the newest Atom processor for tablets and HTPCs.
-wireless speakers - a new standard has been developed and have been shown off at a number of AV industry trade shows recently. Also lots of bluetooth and cloud connected portable speakers.
-wifi based home automation. if Kickstarter would have existed a few years ago this is a place I knew was going to take off. Now big companies like Belkin are getting it on it. Wifi enabled light switches, dimmers, sump pumps, ovens, etc.
