Disklavier

Hi there is anyone aware of a new disklavier model or major upgrade to 
the Mark IV system in the pipeline? I am about to purchase a new C2 
Mark IV that I have been looking at for some time but had to wait until 
my renovations were finished. I would hate to take delivery only to 
find out that Yamaha is about to release a new model in the foreseeable 
future. Thanks.
