I got a little more info from the Yamaha Canada Motif site here:
http://www.yamaha.ca/pma/motifes.html and from YamahaSynth's new site:

-----------------------------
Easy Song Making with new ES “Phrase Factory”Much more than a simple arpeggiator, the MOTIF ES Phrase Factory offers unprecedented versatility for creating sequenced phrases. Use it with the drum kits to produce innovative rhythm patterns, or take advantage of its chord-recognition capabilities to generate pitched phrases using the normal voices. You have 1,787 preset arpeggiator phrases to start with – from standard synth arps to drum loops to natural-sounding acoustic-instrument grooves. The Phrase Factory system works seamlessly with Keyboard Mega Voice technology so you can take advantage of all the expressive Keyboard Mega Voice nuances. You can even assign five different arp phrases to the switches below the display and switch them in real time. Plus the arpeggiator’s new chord recognition and performance play parameters let you easily create your own user arps or modify presets to make them your own. Finally if your creative runs dry, Real Time Loop Remix let’s you generate literally thousands of instant variations on any phrase either MIDI or audio.
------------------------------
This sounds like the beginning of convergence between arrangers and workstations for Yamaha. Having arps/phrases that recognize chords and having these phrases assignable to buttons below the display sounds very much like an advanced arranger capability.
And another goodie previously unseen:
------------------------------
Elegant System Integration with DAWs If you use a computer-based sequencer or DAW as part of your music production setup, with press of a button you can turn the MOTIF ES into a full function control surface that supports the same protocols as the new 01X Digital Mixing Studio. Simply connect a USB cable between the instrument’s “TO HOST” USB port and your computer’s USB port, and you can directly access your sequencer/DAW software’s fader, pan, EQ effect send, track mute, transport, and other parameters from the MOTIF ES controllers. You can even open and close windows on your computer directly from your ES.
----------------------------------
Hey - it's a control surface too! If I can control Reason and/or Sonar with it then I'll be very happy. The Motif ES really sounds better with each new tidbit of info we get.
