Calm down now, this rumor has already been settled. As MaGuS said:
Which is absolutely correct. When FFX-2 was first announced, ages ago now, Square originally intended two seperate games, one called FFX-2 Yuna Version, and FFX-2 Rikku Version. They were going to be the same games, but like Pokemon or something, you could choose, based on which version you bought, which character to play as. However, as they developed X-2, this idea was dropped with little fanfare. As a result, the "lost" Rikku version of FFX-2 was warped into the FFX-3 rumor, which is not true. X-3 was never planned, it was just an alternate version of X-2 that was never created.i'm not sure but at the start, they wanted to make 2 versions of X-2 a rikku and a yuna in which u get to be rikku or yuna as main character.
but i guess they just dropped that idea and maded only 1 story.
The Lulu prequel I believe was an idea of what would be interesting to see if they made another game, not an offical rumor.
Square has no plans presently of doing any more with FFX - they're to busy whoring out FF7 at the moment.
