i was hoping to get a new one at some stage. are they wall warts now?

As far as I know, all the new ones are wall warts.

But the old Mark1-style power supplies were just purchased from a third party anyway. If you wanted to find out who/where, I'm sure you could if you tried. And I think the IBM thinkpad power supplies that work with the Empeg aren't wall warts either, am I right?
