I see your point, but it still doesn't address the weight issue. KR's and Clavinova's don't get lugged around from gig to gig much.

And, without a change in feel of the 88's keys to virtually unweighted, so will most 88 arrangers. The P85 (I've played one) to me still feels a BIT lighter than say a Clavinova or RD700G, and I agree, other than organ, I could probably make it work (I play enough real piano at work and home that my technique hasn't atrophied ), but I doubt anyone could add it to an arranger and stay in your weight range.

Let's face it, the P85 is what? about 25 lbs., and that is with a case that is barely more than a shell for the action. Little in the way of buttons, displays, etc.. and I imagine not much innards. You are only allowing a five lb. difference between the P85 and the S900... Best of luck on that one! I'd guess Yamaha would be VERY hard pressed to keep the weight under 35 lbs. without ditching the speaker system...

Still, 35-40 lbs. is actually the weight of MOST TOTL arrangers, and well under some ( ), so I don't think there would be a sales penalty... You want that 30 lbs. S900 88, I think you would have to have one of the no-touch 88 DGX actions, and there goes your entire reason for the beast!

This is why I still think the NP30/S900 would be Yamaha's best bet to enter this market segment (and bury the opposition). Cheap, light, big enough for most non-pros to get by on piano (few amateurs use the extremes of range, anyway) and no threat to the Clavinovas... or the DGX's
