While it isn't especially earth shattering, class designer Koraa popped into the official Shaman forums (gasp!) to say something simple, yet intriguing. Eronar of Argent Dawn posted a thread asking the question, "Are you staying a Shaman in WOTK?" and Koraa's simple response was, "I think you'll stay." It could be a completely simple statement with no deeper meaning at all, but it isn't like the WoW community to let something like that go without coming up with some kind of conspiracy theory.
Last we knew, Shaman spells and abilities hadn't yet been implemented into the Wrath alpha. Could this be a sign that the devs are planning to move into the testing phase for Shaman soon? That's probably something to be excited about, if the other classes are any indicator. While certainly not everything in Alpha will make Live, things are looking pretty exciting so far, even for the classes and specs that have felt left behind in the past. Hopefully Shaman will feel the same. It's definitely something to look forward to seeing, at the very least.
