Although MPS seems like an interesting project, I cant seem to figure out where it is heading to.
Do you actually have sort of a milestone or release date in mind?
Also although the concepts of easily being able to create DSLs is interesting, how many people do you think really want to do that?
So although I find this project to be interesting, I dont see much real world usage or a market for it.
I would love to see someone from Jetbrains shed some light on this.
