Rammstein's been touring the US solid in bunches for the last couple of years now. Their last leg had like 20 dates or something didn't it? I don't see the benefit to them playing 1 hour on Mayhem in cities which they've already played recently. It's not like they have a new album out or anything. Is their greatest hits album enough to ride on for promotion? A few of those cities they've done more than 1 show (they did 3 shows in Montreal since December 2010, all of which I believe were sold out), but I don't know if there'd be that type of demand in every city. There's just too many reasons for them not to do it.
