Why so much less for the new Oppo UDP-203?

The Oppo BDP-105 is a "reference-like" player with higher quality internal parts(DACs, power supplies, etc.) and a better/stronger/heftier chassis, while the 203 is Oppos version of a consumer model that does 4K, though clearly better than most mfr's "consumer" models.  The 205 4K is the reference model equivalent of the 105.

Also, no streaming is built in.

The 205 is coming next year.  They've been clear on that.

I couldn't find any info regarding the remote and volume control.  Does anyone know if these new models with have built in remote volume control as the other Oppos have?

@lcherepkai , Yes, Oppo UDP-203 does have built in volume control. I have been using it for over a month now, fantastic audio and video player.  

Upscaling to 4K is simply amazing. Don't care for missing streaming apps as my 4K TV got all the latest apps. 

Oppo just posted UDP-205 picture on their site. I have noticed they have dropped the 103 and 105 from the menu. So I guess they are no longer available through Oppo.
