PSP Games Coming to PS3 with HD Visuals and Extra Content | PS3Blog.net
Sony has announced a new initiative where select PSP titles will be ported to the PS3 with improvements (think dual analog sticks) to each game. They are calling this movement Playstation Portable Remaster Series.
All games will display HD graphics but some games will have 3D support, new exclusive content, control pad support and more!
Game saves will still be interchangeable between the PSP and PS3.
To get an idea what we are to expect, check out the Monster Hunter Portable 3rd up above.
Edit: Rumors are flying around that the HD versions of these PSP games will be compatible with the NGP which makes sense. Lots to look forward to!
