I would agree on Airbus Lovers comment regarding the MAS 734. I don't think that it is their first priority to replace them.
Just to note that MAS 734 are not only operated on domestic flights. They also fly it to MNL, DPS, HKT, PNH, SGN, HAN, RGN, HKG, CEB, MNL, BWN, etc
I rather would see them to replace F50 or DHT's.
