The Sage/Faroudja chips will be appearing in a large variety of units, including DVD players and projectors. Kenwood has a DVD player scheduled for release (I have seen it), and Infocus LP530 includes the Sage chips, and Infocus' new HT machine will have it as well.
I spoke to the Sage rep at the SID show a few weeks ago, and he said that they are being very aggressive about new contracts.
Their main competitors are the Genesis chip set and the Silicon Image set. From what I can tell, the Sage and SI sets are very similar on 3:2 inverse-telecine (for film material). Sage wins on video-based material (which requires a heuristic approach to scaling) and also has better color rendition.
In summary: this is not going to be a unique feature for Marantz or NEC, but should become fairly common within a year or so.
[Edited to say "Kenwood DVD player" not "Kenwood projector".]
