I'd agree those languages are converging to the same feature set, but the features they're each really good at does differentiate them. Typescript is good for Javascript generation. Kotlin and Eclipse Ceylon are good at generating statically typed JVM bytecodes. Apache Groovy's good for those 20-liners in Gradle for specifying builds on the JVM and Android. Kotlin's good for Android code.
