If anything they will just use Double$peak. They could release source only for the same code they document now for developers and hype their "New Open Source Windows 2002!!!" while key aspects of security and interoperability features are quietly kept closed.
I wouldn't bet on any right to make your own mods, either - there will probably be the usual unilateral license "agreement" that you invoke by just looking at the code.
