I'm very close to pulling the trigger on a purchase of the 55" LG B6. My 46" Panasonic plasma is pretty old, and I've been patiently awaiting something that I consider a genuine upgrade. LCDs and LEDs just haven't impressed me enough to buy any of them. This TV appears to meet my needs for movies/ streaming and gaming for a pending PC upgrade and PS4. Is there anything I'm missing as far as a new upcoming technology or far superior model that would make this purchase a bad idea? Most reviews are very positive. The few negatives are no 3D (wasn't looking for that anyway), mediocre sound (never use TV speakers ever), and mediocre/ average input lag (this is the one I dislike). Any suggestions or warnings? Thanks.
