Well it really depends on which model of the psp you have (psp-1000, -2000, or -3000) and i'm not sure you have heard, but a new psp is probably going to be anounced at E3 (psp GO!!) which will have a slide up screen and have completely downloadable games and no UMD disk drive which allows for a longer battery life. This new model of psp will also be changing to a new model of memory stick which will be less expensive and have lower loading times and since the games are downloadable they will most likely be cheaper than the disk based ones. Though Prototype and Batman: Arkham Asylum may look brilliant, i would recommend that you buy the new psp that will be coming out relatively soon, especially since you enjoy Monster Hunter games so much, but the end choice is up to you.Save up for ps3 or buy prototype and other ps3 games?
