Hi Ed,
I don't think I can. I work in an academic environment and we don't have a large customer base that we'd have to migrate etc. And the Xtext developers are certainly aware of the potential benefits of ANTLR4. I am not sure if those benefits are enough to justify a migration.
That being said, ANTLR4 certainly has huge benefits. One of many reasons to develop our ANTLR4 based modeling infrastructure is that ANTLR4 simplifies grammar development a lot. We tested with several grammars from the https://github.com/antlr/grammars-v4 repository. I had a basic Java8 language infrastructure up and running in about 2-3 hours (we basically just added labels to the ANTLR4 grammar). While ANTLR3 is often faster, new grammars are more likely to be developed for ANTLR4.
Regards
Michael
