No idea. Paulaner is the only one I've found.
Edit: I just found this one:

HofbrauHaus from the descriptions is a "yellow" beer, so maybe that's it.
Next year, I would suspect that a certain brewery in the Denver area will make a weisn bier. I've already planted the bug in my friends ear about doing it... His marzen is a big seller in the Denver metro area though, so it may be a little tough to bring competition to that beer.
