Python support in Intellij Ultimate is also "just a plug-in". Adding the plug-in gives equivalent functionality to running the stand-alone PyCharm. Apart from that, the support for Scala is not at the same level as the support for Java. Given the differences in language complexity, it is much easier writing tools handling Java code than writing tools for handling Scala code. Combined with the scale of markets, I would be very surprised if Scala support was even near Java support. With that said, I can't get Scala to run in my IntelliJ 14 install, so I'll have to stay in 13 for now. Sigh...
