This is my case, I will have lots of entities on screen, ~1000 vertices each, vertex animated, 4-6 frames per animation, only ~4 models, but many of each type (ranges from 1 to 100 each). My hopes are that model instancing and GPU powered animation will reduce the workload for it (in the future)... so, is it a big deal to do it when you have finished some of the more important stuff?
