EB Games has a listing for Heroes of the Pacific on PSP. While the game's official site hasn't been updated to reflect this, it seems likely this listing isn't a mistake. After all, Heroes of the Pacific already came out on PS2, so it should be a relatively easy port (assuming it's a port and not a new entry). For those that don't remember when Heroes first came out, it received much critical praise and was heralded for its impressive dog fights. The game is listed as a 2008 release, so it may be a while before we find out more info on Heroes of the Pacific.
