I agree that the MMX series should've ended at X5, although X6's story & characters were intruiging, it did seem forced (it's as if Inticreates wanted to make a MMZ5 & MMZ6 [no i don't mean ZX], just because they felt there was still more room for story, despite there being a satisfying end to this sub-series already in place). The entire saga up to that point was leading up to X & Zero inevitably fighting each other, Wily's ongoing influence, etc. X5 was the climax of all that, and the sequel series MMZ was a continuation of the legacy. I felt the remaining X games just muddied up the waters & IMO somewhat tarnished the legacy; I could go on & on but that belongs in another topic, def not here.
How long does Dracula in this version reign?
I recall Cox tweeting that Dracula hasn't fed in over 100 years, which is why he looks so decrepit in current times. Guess we won't know for sure until the game is released.
