Neither Daimler-Benz nor BMW sent a rep to the initial manufacturer's meeting, did they? As for Mazda, I don't think I've heard their name come up before either. I have heard a rumor that Roger Penske (Ilmor?) is working on a badging deal with an OEM - and it's not Honda. But I don't know who it is. It sounded rather odd when I heard that, but I don't know what Ilmor's current relationship with Honda is.

As for Ferrari, that name tends to be brought up by people who don't understand the relationship between FIAT and Ferrari. To them, they hear "FIAT", read that FIAT owns Ferrari and then they put 2 & 2 together and get 7. Maybe Maserati was a possibility at one time. But I thought that both FIAT and Porsche had dismissed the idea of producing an engine for the series. Maybe something has changed?

As of right now, all I really expect is Honda and some cobbled together vapor deal from Kalkhoven/Cosworth.
