Are you sure the new BMW's use SWF? The E70's wipers look almost exactly like either Valeo Ultimates or Bosch Icons. Valeo SWF's are a different "style" altogether (go to their web site) and don't look anything like the ones on the E70.

The Bosch rep told me that Bosch is supplying them for the new X5 but they are not Icons, rather they are the ones available on the German market called Aerotwin (I believe). Not sure how true this is, but that's what he said.
