With the key word being photography I'm surprised more wouldn't say P4P. The camera is so much better. I have a P4 I was gonna hold onto as a back up but not anymore. I could never go back to shooting that camera. With that said the P4 camera is amazing as well...but in my book P4P is superior. I was in your shoes this summer, p3p or p4 I went with P3P and had it a month before getting the P4...If you get P4 now and then decide you want Pro, you will lose a good chunk of change selling the P4...much to think about.
