The cost and engineering a complex/effective room correction system is not trivial. I would not be surprised that the next release from Oppo wont have it. At best maybe Oppo will implement a 3 to 6 band PEQ on a per channel basis - most likely to the analogue section. This would correct only the frequency response but not in the time domain.
An external box solution like the miniDSP DDRC-88A seems logical. It allows one to apply room correction that is independent of the up-stream audio chain such as the receiver or pre/pro or universal blu-ray player, etc. It would sit in the correct part of the audio chain, where the bass management, volume control and tones are done up-stream.
If you connect the future Oppo with both HDMI and analogue pre-outs to your receiver or pre/pro, will it apply correction filters for the analogue signals? Most wont.
Most of the issues for room correction are at 500Hz and below.
