Fans have discovered unseen scenes is this legendary rpg. however it is only on the japanese version. 

Main point across, seeing this brought this to my mind. Its been years and people are still nosing around and trying to find new stuff in FFVII. How much more does SE need to see from fans?  A twitter page that exploded at the mention of such a possibility, and millions of fans and countless of petitions. 

`maybe they are poor and can't afford a ps3 or 360 to buy FF13... >_>

Interesting. It's like whenever people found out about the Master Hand glitch in Melee that came out a year or two ago.

What is the basis to claim this wasnt found out before?

simple. have you heard of or seen this scene before? case close. they can only be found using things like gameshark etc. They were left out, but they kept it in the game, maybe by accident, who knows.

Also I'd add the music in the scene is called "Comical"; an unused track heard nowhere else in the game.

Does anyone know what they're saying?

I think they're speaking japanese.

Translation summary by Annachuu.
"What I could make out was that Palmer was having fun at the Honey Bee Inn, and when he asked (incredulously) what the manager was doing there, the manager replied that "he was there for marketing purposes", in which backfired when one of the Honey Bee ladies implied that the manager was a regular there, esp with said lady. What's more, that very Honey Bee lady happened to be Palmer's "honey" and Palmer was obviously not very happy about this and chased the manager."

I think more research is still in the works lol

lol i know. I even think that if SE were to ask people for donations to help make the remake hundreds of thousands of people would jump all over that.

The fact I hadnt heard or seen the scene doesnt mean it wasnt found out before, what kind of logic is this. Theres a multitude of things I hadnt heard or seen before and obviously it doesnt mean it didnt exist before. Since you were going to give the answer in the second phrase "they can only be found using things like gameshark etc.They were left out, but they kept it in the game, maybe by accident, who knows." im really wondering what was the point of the first one.
