Is it already the defacto Blub language? No.
Do I know anyone in my field who isn't at least aware of the proclaimed advantages of Scala (I'm in industrial computer science research)? Also no.
The first camp follows Oracle/IBM (Microsoft if we are talking .Net shops, not related here) and they follow the second.
EDIT: also, forget for a second the "mindshare race" bit. Already people are commenting "why did they do this? it's just like Scala". Now, obviously Scala and the other JVM languages weren't in the same state two years ago. Maybe then it was logical to design your own language with then-new language features and expressibility. But if it wasn't so top secret, people would notice the duplication of efforts and perhaps merge the two projects when this was just an idea. Maybe I'm wrong, I admit I haven't had the time yet to actually see more than several lines of Cylon, but from the comments and the highlighted features there was some obvious duplicated effort.
This is where Ceylon / Fantom are interesting: they improve a little on Java, removing the various language warts, while not being too different.
That being said, I'd love it if Scala were the next Blub language ;)
Having said that, while I do see Scala at conferences and in articles, this hardly qualifies as a sign of gaining momentum, and job boards hardly register Scala in the top 50 languages.
