According to this report from the Mega Man Network, copies of the PSP Mega Man Dual Pack (which includes the remakes of Mega Man 1 and Mega Man X) will be limited to a print run of only 10,000 copies and sold exclusively by GameStop stores in the U.S.A.
A future collector's item indeed. Now seems to be the time to invest $15 in purchasing this compilation of Mega Man Powered Up and Mega Man: Maverick Hunter X before it is too late.
