Patrick said you need to include a note on the form to ask for an upgrade to the MMpro- its not an official thing yet, and you will join the end of the queue since MMpros are in short supply (specifically the FETs). Its $75(?) to upgrade to the MMPro, otherwise if the esc is less than 12months old and no rewiring has taken place on the esc itself, standard warrenty replacement/repair will be free (+ shipping).
