I hope so. They would have and some code/features left over from a decade ago when you could write "java" code in Visual Studio as VisualJ. Conceivable the interfaces for hooking the debugger, the syntax highlighting, and all that jazz that VS already has to support could be (re)extended to support the JVM and JRE once again
Doesn't look like it; looks like it's all based on open-source tools written by third parties. Syntax highlighting, Java project support, and the debugger come from the Java Language Support VS extension [1], and Intellisense support is being pulled from a bundled Eclipse instance running the Eclipse Java tools.
