The A1E excites me. So does the LG wallpaper, which, I actually think is fairly priced at $8000, if rumors are correct. However, as someone who uses a receiver, center, and front channels, I wish that the manufacturers would just make a pure panel, no fancy speaker technology or soundbars to jack up the price needlessly.
I'm not saying no speaker (although I wouldn't mind that either), but don't waste time or money on bleeding edge speaker tech that's going to inflate the price of the panel when all I care about is the picture quality.
(Holds breath for A1E pricing)
