In the long run, the Grimm would most likely be the major antagonists. It wouldn't surprise me if there was some kind of King of Grimm - and Acnologia-type that the heroes have no hope of beating the first few encounters.

I bring the idea that Grimm may evolve because of the appearance of the Ursa Major. I want to believe that the Ursa Major used to be the Ursa that Yang slapped around in the Emerald Forest - we didn't see her kill it exactly, did we? And that encounter forced it to rapidly grow stronger.

Ironwood might not do it intentional - I don't think he considers the Grimm able to evolve - but his machines may inadvertently cause them to grow stronger.

That's just a theory anyway.
