That would be the only reason.  The cost of replacing existing 2TB 
drives with 4TB drives seems pretty high.  Performace would only go 
down, and if the physical block size increases, then storage 
efficiency would decrease.  Disk bays are not necessarily all that 
expensive as long as there is a place nearby to put it.

An existing disk chassis could be replaced with one which supports 
more slots and the existing drives re-used as long as they are 
physically compatible with the new chassis.
