I've preordered the game and can't wait for it to come out next week. FFX is probably my favorite FF (maybe with the exception of Tactics?) so I'm hyped.
I'm not really looking forward to modified OST. I hope it will be better, but it was already pretty damn good and nostalgia will probably push it out of reach.
I'm less enthusiastic about X-2. I'm willing to give it another shot, but I'm one of those people who felt betrayed by X-2's tone and direction. I never finished it to see how it all ended and have managed to not to spoil the ending all these years so here's to giving it another chance!
