the similarities between echo and DmC arent really that big...i mean you COULD say NT may have drawn inspiration from some things. but a lot of things eg ranking system, multiple styles etc were present in the old series. i find it hard to belive that any of the past DMCs were copies of anything. i mean i could argue inuyasha stole its idea of a plot from the millions of other classic demon/human (general unworldly being hybrid) hybrid stories that have been told through history. DMC1 was orginally a resident evil game but even then i couldnt tell until someone pointed it out to me.
