I also saw the prototype, in 2000 as I recall. It was scrapped when the decision was made to go with what New Holland had in the works for several years with the CR_CX combine, and to make a differentiated version with a single rotor, the 8010. A few concepts were borrowed from the big Case prototype I am told by qualified sources, such as the returns system (which has thus far not proven successful) and the CVT rotor drive, and header drive system. This is an interesting topic. I wonder the effect of bumping the 8010 to 460+ hp. Would the drives handle it, and is there enough rotor capacity to be able to effectively utilize that powerIJ Certainly the single rotor combines will reach the processing limit long before the Cat will, but what could they do outside of lenghtening the rotor to gain capacityIJ My contention is that it will be incredibly difficult to exceed, let alone match, the mark set by the 590R with a single rotor processing system. But that's what new hot shot engineers are for. In any case, the 8010 is far closer than the STS is.
