I think this echos what people have been saying for a while. Current mainstream home entertainment (TVs, DVDs, CDs, etc) are good enough for Joe Public.
Geeks, Hi-Fi buffs, etc. will no doubt say that Blu-Ray, Hi-Def, etc. are *so* much better. But Joe Public doesn't care.
I suspect all that Joe Public wants now, is just lower price. (Oh, and for it to last a long time - just like their old, CRT TV did)
