What's the difference between Intentional's product and JetBrains' MPS? To me it seems like MPS can do much more and can accommodate Intentional's model as well. Anyone knows better?
It's hard to know. Intentional asks people who they show the product to, to sign a restrictive NDA, so they can't share what they do. I hope, after MS acquired them, they will release it under less restrictive license.
