Roland just introduced the Fantom X series of Keyboards and by cracky if they don't have the Fantom XR Rack Mount too for those looking for a Module. The Motif ES has been out about 5 months now and NO mention at all of an ES Rack. Kudos to Roland for releasing an X series XR Rack Mount at the same time as the Fantom X series Keyboards.

Here is the info and specs of the rack: http://namm.harmony-central.com/WNAMM04/Content/Roland/PR/Fantom-XR.html
