"The blending of the PS2 and PSP continues as PSP's Ratchet and Clank: Size Matters is marked for PS2 release early next year. A GameStop listing says the game is expected Feb. 12, '08 for $30, but consider this a placeholder for now.
Ratchet and Clank: Size Matters joins a solid list of games that made the jump from PSP to the PS2. Most famously at this point are the ports of GTA: Vice City Stories and GTA; Liberty City Stories, both of which ended up on the PS2 at the delicious consumer-friendly price of $20. We wouldn't mind seeing God of War: Chains of Olympus make the PS2 leap by holiday '08 -- but let's just get the thing out on PSP first."
