Out of all those listed it's wrong that the MO series is going up considering the sound set is from the dated Motif ES..., and there's better options out there now. Yamaha should keep those prices on the MO's exactly where they are so they can keep buyers for this aging line.

The MO6's challengers are the Korg M50 and Roland Juno-G.... The Juno sells for the same price, but does more. The M50 is just about $100 more, but it too has bit of a lead on the MO line.

Sounds like a classic "sales booster" run. Let the public know you're going to jack your prices.., so get your orders in now before it's too late. I wouldn't be surprised if Korg or Roland dropped theirs a few bucks just to give Yammie the middle finger on this one.
