Bourne 4??!!!

Now I love these films as much as the next person...but a fourth film will just be ridiculous!!!! What will the story be; Bourne starts a job in the government after what they did to him! Bourne Ultimatum felt like the end, he had gone full cycle, the premise of these films was that he had lost his memory and was fighting to remeber who he was and to stay alive. By the third film he had remembered everything. If they do decide to do another Bourne movie, it will destroy any credibility the first ones had and it will be more like James Bond... a never ending story which will just frustrate the original fans..PLEASE DON'T DO IT!!!
