eh, i'd have to disagree about any real sort of mark, capcom seems to ignore it for the most part and from a business perspective they really should, it sold more then dmc1, but they know fans aren't going to be caught off guard by something like it again and that dmc2 has a.... reputation among the players.
sure it gave us rebellion, but only in name, a sword from dantes father was an element from dmc1 and the special demon blood awakening powers or whatever it has weren't really part of anything until dmc3, and i think that the name rebellion was kept either because, capcom hired a writer who is STILL in the "cool names equals cool characters and important mcguffins" phase (dear pazuzu, i remember the stupidity of retarded names like "seraph" that stuff only works when you make up a new word, otherwise it's ham-fisting a stupid idea into an otherwise fine character to make them "edgy" or dear pazuzu "goffick" as seen by the GENIUS here

, i'm going off-topic now) or they wanted to keep some sort of coherent consistency within their own fictional word.
i guess it could be argued some design choices for future dmcs were incorporated, but only if you really bother trying, and then again, that doesn't redeem a game with stupid "escape the explosion with a stupidly long fuse while i refuse to tell you where the hell you're supposed to go" level.
