They do not.  In fact, when I purchased my DC3A, part of the "sale" 
was how Yamaha always provided an upgrade path for the control 
devices (e.g. adding CD capability, etc.).  I understood that the 
internal components of the piano can not be easily be upgraded (e.g. 
solenoids, silent system).  However, Yamaha COULD provide a complete 
replacement for the Mark III control box to have Mark IV 
capabilities, but obviously they have decided not to.  A real shame 
in my humble opinion.  There "upgrade path" ended with the Mark 
IIIs.... My only upgrade option now is to purchase a new piano.  
Horrible customer focus.  SJ
