PSP Ratchet title heading to PS2?

Retailer and ratings board listings indicate February 2008 release on PS2.

Video game blog Jotstiq has noticed a new listing on the website of US retailer GameStop for a PlayStation 2 version of Ratchet & Clank: Size Matters. Originally released for PSP, if the retailer is correct the PS2 port will be in North American stores on February 12, 2008.

To add some weight to the rumour, the US Entertainment Software Ratings Board (ESRB) has the game listed on its website for both PSP and PlayStation 2.

Ratchet & Clank: Size Matters will join several PSP titles that have made the jump to the PlayStation 2, most notably the PSP GTAs. Konami's Silent Hill Origins is also rumoured to be on its way to PS2.
