No worries! I'm not here to convince anyone but myself of the merits of the OPPO, I genuinely think it'll be a classier all-round piece of kit but time will tell, natch. I'm happy to spend the next couple of months without a UHD player as I've greatly cooled on 4K anyway, which begs the question "why bother spending that much on the OPPO UHD then?" but the current OPPO SKUs have been around for a good few years already so the prospect of getting a brand-spanking new (as in, internal decoding) model is enticing in itself, to say nothing of the UHD functionality on top.
There's also the possible upgrade to Dolby Vision to come which will make the player an excellent long-term proposition, it'll probably lack dynamic HDR10 but as long as a TV maps static HDR10 properly then that's not an issue (though the correct mapping has been rare of late, admittedly).
