Eh...I dunno about CotM3 (though I'd be elated for it), but both RoTN and I assume RoTN2 are proceeding apace. For RoTN, yes, there have been delays, but 505 is still attending to the official Bloodstained discord and they've told us work on the remaining modes is continuing well, they've provided roadmaps, etc. Now, there could be more delays in the future, sure, but that's software development unfortunately. I think the game itself is definitely on the road to full completion, even if there were a few delays.
As for RotN2, well, I know nothing about that other than what's been publicly revealed (namely the leak lol) but if 505's still working with Artplay, and again they are judging by their updates on the discord, IMO it's safe to assume work on the sequel is proceeding at a satisfactory pace, since with 505's involvement from the very outset they'll be able to help IGA more with everything and keep development on track
