So I picked up a copy from Amazon. So I am waiting for it to get here and I am thinking should I have waited for the PSP port?
 
I am thinking not, as I am not sure how much will have to be taken out of the PSP one. The only thing I really thinking I will miss is the ability to directly control characters other than the Protagonist in battle.
 
Dose anyone one think that this will really make that much difference? 

Do you play your PSP much? Because if you don't, then you might as well get the definitive experience.

I only played it for 3-4 hours before i stopped so take this with a grain of salt. The way you navigated around that place is very annoying and overly complex. Its not bad and gets better once you memorize everything, but if your going from p4 to p3 it will feel ancient at times. But other then that, and a few bad choices in menu layout its pretty much the same. The PSP version might fix a few of the things, but i don't think it will be anything major. And if they use that old school dungeon crawler system for moving around the world like they did in the Persona 1 Remake your better off not playing it imho. I hate that kind of thing even worse. Its fine as it is on ps2, even with the few quality of life things missing from newer versions of the game and just more modern RPG's in general.

Voice acting and probably some other stuff will be taken out for UMD space probably

Yes.  It makes the game very different, but you'll get used to it.  Besides, don't support Atlus' second re-release of the game.  FES is fine. 

Thanks to everyone for your help. I am still waiting for it to come in the post.
 
I may still look at the PSP one just to see what they did.
