My first experience with the amazing God Of War series was actually on my PSP. I'm now enjoying the PS3 remakes of the first two games in preparation of delving into the third. God of War: Origins is a new compilation pack that will include remakes of the original portable titles in glorious HD. This project is not a simple upscaling, but will include new artwork, assets in more. Check out this video to see what is in store.
From the looks of it, I think that both players who have never played the excellent Ready at Dawn-developed titles and players who have enjoyed those excellent PSP games will have a reason to open their wallets when the game launches on September 13th.
