Good news for those of you purchasing the Irregular Hunter X/Rockman Rockman value pack from Play Asia: the bonus soundtrack will be included with the initial value pack shipments. A PA rep informed me they will be receiving a limited amount of soundtracks, thus supply will be constrained and probably won't replenish.
For the uninformed, the soundtrack contains 30 tracks of music from both IHX and RR. Unfortunately, you won't be getting the entire IHX/RR score, most likely select tunes.
The value pack ships September 17th, 2009.
