Personally, I hope real time combat support gets added to the D:OS engine and more dragon knight RPGs get made (I like turn based combat, but don't see how it would work well with dragon flight).
Yeah, same. Although I didn't actively dislike the turn-based system, which I thought would be the case, it still felt a little awkward and clunky rather than nostalgic, but I guess I was never much of a fan. :P
Other than that, no complaints about them using the same engine, though. But I do sometimes wonder if I'm one of an apparently small group who really enjoyed the way D2 was presented!
