New Persona 4 related teaser site

A few days ago, this website went up: p-atlus.jp
There's not much there yet; just the URL on a coloured background. But I'm sure we all recognise the font and colour choice...
So, what do you think it is? (My money's on a 3DS and/or Vita version of Persona 4).

It's gonna be P4P or a P4: FES or something similar.

I'd be certain it's something Persona 4 related, given the font and colour.
I doubt it's a straight directors cut version, as I'd be fairly sure even Atlus have now given up on the PS2. And it won't be Perspne 4 Portable as such (i.e. it won't be on the PSP), because they have that they won't be doing a PSP version of Persona 4, as for P3P they had to compromise too much to make it fit the UMD.
But as I said above, a 3DS and/or Vita version is certainly possible (and remember that Atlus have long since confirmed that there is an unspecified Persona game being made for the 3DS).

They can make it downloadable for PSP which means it would be playable on Vita as well. That would still make it P4P for all intents and purposes (even if it is on 3DS or Vita instead it would still be considered P4P).

Also, any directors cut or modified release would just come out on PS3.

Oh, I agree that it would be Persona 4 Portable in all but name. But semantically it wouldn't be, since if it's not on the PSP, they wouldn't subtitle it 'Portable'.
As for a PS3 director's cut version, I think it's very unlikely. They'd have to greatly improve the graphics to put it on the PS3 (to avoid accusations of laziness, incompetence, etc.), and that would cost too much and take too much time (money and time better invested in making Persona 5).

A Director's Cut version would be released on PS3 simply because it would sell more. Look at Disgaea 4; it doesn't push any limits of the PS2 I would bet but it is on PS3 because that is the new console.

P4P would still be called that (unless on 3DS) because it's a portable version of the game. On 3DS it would be called Persona 4 3D or something though.

Well they got me, I guess it's going to be called "Persona 4 Golden".

Here's what I've gathered:

Persona 4: The Golden is going to be a Playstation Vita upgrade of Persona 4, much like P4P. Will have 50% more voice, added anime cut scenes, a new character, and probably some other things.

There will also be a Persona based fighting game. Has the cast of P4 and looks like some from P3. This may be the "Persona 4 Ultimate" you heard of. Will likely be similar to BlazBlue/Guilty Gear in style.

Atlus said that the plot is figured out and that type of stuff, but it will be a while before any release date or even official announcement.
