Unlike Scala it compiles down to Java. Depending upon how readable and sane the generated code is, I could see people working in organizations where Java is mandated write code in Xtend and then commit the generated Java code or use the generated code as base for code that get committed to official channels. Although I'm skeptical of how readable the Xtend generated Java is.
Doing so would mean it would need to be super friendly going the other direction. It'd be really annoying working in one language, compiling to java, having someone modify that java, and then needing to read and work through everything in java now.
