I will not buy an M700 or another M-player until it can decode to LPCM 7.1
Now that the M700 is out and they have a Blu-Ray system they can market, it seems that the two biggest items that K* should add to the M series players is LPCM 7.1 and 3D capability.
I think those 2 features would give virtually everyone what they want for a system that stores all DVDs & Blu-Rays.
