GameStop.com for a "Mega Man Dual Pack", a Sony PSP SKU due for release on September 5, priced at $14.99. Very little details are available this time, but we can assume product to be a bundling of two PSP Mega Man titles, likely Powered Up and Maverick Hunter X.
I say "likely" because we also can't rule out the possibility Dual Pack consists of the PSP Mega Man Legends ports. These titles never released outside of Japan, but perhaps Capcom saw fit to bring them stateside now to flesh out the PSP's thinning library... maybe. Having not been confirmed by Capcom, however, it's difficult to determine just what's inside Dual Pack.
Hopefully, more details are forthcoming. I'll see if I can weasel out a comment from Capcom. In the meantime, feel free to hop aboard the speculation train!

Thanks for the tip, Andrew
