This year's CEDIA has come and gone, and unless the journalists in attendance badly missed something, I didn't see many announcements with broad applicability outside the core custom install base. (I attended CES and IFA this year, but was not able to attend CEDIA live.)
Sony showed off new projectors, including a native 4K model priced at "just" $10,000, but these had been announced at IFA in Berlin.
JVC introduced a trio of projectors from $4,000 - $10,000 that create pseudo-4K from 4K source material.
Kaleidescape is now offering a 4K digital storage/playback solution in the $5000 - If You Have To Ask, You Can't Afford It range.
There were no new budget projectors announced; those seemingly will wait for CES. There were few new AV receivers, relatively little new home automation gear, and virtually nothing on the Atmos or HDR TV fronts. The exception: Sony's STR-ZA5000ES, a 9-channel, $2700 receiver with Atmos and DTS:X.
