Good Lord, this is worse than I'd feared. They're going to get dragged through the mud and pay a hefty sum for the privilege.
NewTSRs only hope here seems to be WoTC quickly getting the case dismissed (likely on jurisdictional grounds - an almost certain slam dunk) and then choosing not to pursue attorney's fees (maybe because they don't want to be seen as dunking on the little guy). But their more likely strategy is to get it dismissed quickly then bury NewTSR in attorney's fees just to discourage future action.
