I think they have heavily indicated that there will be additional races and classes down the line though; the last newsletter made a point of putting "launch" before the class/race lists and they also used the words "at launch" a couple of times during PfH too iirc. So unless they're giving us those for free (would be odd since development would be costly) expansions seem likely to me.
My read on that language was a little different. The vibe I got was that he was specifying "at launch" for the folks who need to hear it multiple times and multiple ways that there were no new patches on the way.
Some folks might be half watching while doing something else, fire up EA, and be surprised they can't find the monk, because they just Swen demo it
Communicating with very large audiences is really, really hard to do clearly and concisely
