I could well imagine that there is a gap in the market between the currently available turboprops and the armada of regional jets (C-series, Embraers, the Superjet etc..) - wouldn't surprise me if they would present a large and economical turboprop (or even UDF?) for short to medium sectors. Interesting stuff. On the pax experience: I remember the Saab 2000 as very comfortable and a LOT quieter than any Dash or ATR I have been on - just the cabin felt a little cramped (on Crossair at least).
