Because I think they should, I know that quite a few people will hear a game is going to be released that they like, such as Valkyria Chronicles 2 or God of War, just to find out that it is being released for the PSP. now I am not sure how difficult it would be for Sony to do this, and I know that this isn't what the people who want to play these games want to hear either, but I feel it is a good compromise that would allow more PS3 owners to experience those great PSP titles without having to buy a PSP.
