I have heard anecdotes though about 1.0's Alpha test that MSK and 1.0 ACN did get to a playable stage and were in fact playable by testers, but for whatever reason were quickly removed and never brought back upon 1.0's release. Whether that is true or not I cannot say, as I was not on the 1.0 Alpha or Beta tests, and NDA would still probably be in effect for it anyway, so it's entirelly possible it's just an urban legend.
