The existing 70" was the Qualia 006 and was originally $13k. That technology (basically) went into the SXRD 60" last year at about $5k, now down to about $3500. Their is a new SXRD 60" for $3499, but it is NOT this XBR2, which is $800 more. Confusing, it is hard to see much differences. Visually the speakers are on the sides, which most people (me included) hate because it usually forces one to a smaller size. I heard the 70" speakers were removable from a saleman, but unsure. Hope 60" is as well. The non XBR models have the speaker on the bottom, which people like, except it is silver and distracts from the otherwise nice black surrounds.
