According to Audioholics Oppo reported to them that Lexicon’s engineers did work with Oppo’s to improve some things mainly in video performance. However, those changes were incorporated into the stock BD-83.
The BD-83 has a region free mod so I imagine a mod will be made for the new one shortly if not already. My original Oppo is region free and I don’t have many out of region disks and can crack the region coding on my PC if need be anyway so for me it was a non-issue for the BD-83.
