The word on the street is that the MD95 rumor is a good one - it would be a separate category, though, due largely to the overhead panel.

Eventually, 1/3rd of the MD88/90 fleet will be MD90's.

There are also several vendors involved in a bidding war on pimping out the maddog dashboard - looks sweet - all glass ND and PFD (I mean real glass, not what is there now), standby instruments are glass, and the flat plate is gone and replaced with a big-ass screen. Good for RNP stuff.

Seems as though the MDxx series is here for the long haul.
