Reply #1: Personally, I doubt it.

I know that there are some serious attempts out there to do so, but it's my feeling that language change is far too idiosyncratic to predict.

I am aware of some kind of project which tracks on going language change in the spoken form, by doing periodic interviews which include recording people. I do know it has tracked pronunciation changes that the users are generally unaware of. I saw a show about this on PBS a decade or more ago. Perhaps someone could look at several decades of that research and attempt to project into the future.
