I'm transcribing from an Audio Interview with Peter Moore, where Peter Moore talks about the warranty being extended to three years, and also, later in the interview, Major Nelson notices that Peter Moore is wearing long sleeves.

Time: 5:08

Major Nelson: Now, I'm looking, cause you have long sleeves on, but I'm looking for the tattoo. *laughs*

Peter Moore: [...] There's all kinds of betting, if I'll have a tattoo, if not, where, and then one, one blog determined that I'd probably get divorced by the end of the night from my wife because of my tattoos.

Major Nelson laughs.

Peter Moore: So, you'll just have to wait and see.

So, will Peter Moore have a new tattoo at E3?
If so, what will it be of?

You be the judge!

Edit: Updating with a link to wired.com's interview, discussing similar things: http://blog.wired.com/games/2007/07/interview-micro.html

WN: And finally, having used both of your arms, what are some possible locations for the tattoo that you'll be showing us at…

PM: Yeah, yeah, yeah.

WN: Hey, I'm sure everybody's already asked you this, but, you know.

PM: Yeah, I see there's already betting on what I'm going to be tattooed with and where. I have a lady with me, so we're not going to get into this.

WN: That's fair.

PM: If you want to see that, you'll have to be in Santa Monica on Tuesday night.

WN: I'll be there with a camera.

PM: Cheers Chris, take care.

WN: Thanks, bye.

Tattoo confirmed! But of what?!?

I would die of hysterical laughter if he tears open his shirt and has "MGS" or "FFXIII" tatooed in the middle.

That would definitely be the greatest PR stunt of all time. Totally blowing anything Shiggy or Reggie have ever done out of the water. ^^

Apparently rumor has it there will be a picture of solid snake on his...

I have a great feeling what it might be. Its not MGS 4 since it will be at Sony and Konami E3 conference. I might be TEKKEN 6. On the official TEKKEN website theres all the versons of the Tekken seris from the PS1, PS2 and arcade. However when it shows TEKKEN 6 its says arcade and mentions nothing about the PS3 which is quite odd

I don't think it will be FF XIII or MGS 4 but there might be something else. It's not gonna be something as big as GTA IV or bigger that was untoppable.

hey it could be Shenmue 3. seriously Peter Moore was a big fan of the seris

 Yeah but that's not a PS3 exclusive. That's not a tatoo worthy announcement lol

gonna be a big "we sorry our hardware sucks heres a coupon for a lap dance"

The 360 a great game system and so is the PS3 Woof. Fanboys these days. Anyway it has to be something big since Peter Moore has a tattoo maybe Ninja Gaiden 2, TEKKEN 6, FF7 remake will idk cant wait for E3
