I would agree. Between the fact that new companies aren't generally standing up mainframes, and that existing companies are finally getting off them (I know one bank locally that's migrated critical parts of its payments processing to commodity hardware & languages, and the most critical government payments processing system) I suspect it will be a shrinking market. I certainly wouldn't bet on an uninterrupted career out of it, put it that way.
