I'd just like to say Creyk that I think it was less that we didn't think it'd be possible and more that they wanted a source on why you said it, because right now with how that was typed/worded seemed very "Ha! Take that you naysayers/idiots!", it feels like you didn't get that we just wanted a credible source, or at least a reason other than personal gripes. And, at least in my case since, yes, at that time, it was just a, very possible, possibility that I didn't hope come to pass if only because, as you said, that felt lazy.
But back to the part actually about RT DX, at least now we know for sure. A little disappointed but, well, I'm still glad about the addition of Mega Evolution. Yeah, it was in SPMD, but I love Mega Evolutions. So I'm not complaining.
Though it makes me wonder if they'll do DLC considering what they did with SwSh and that it didn't have any data in the base game for Pokémon in the DLC.
