TitaniumZ,
Considering the amount of work and effort that have been put on this big FF13 and FFv13 titles, it's certainly worth to get a console for the title. What you can do will be selling your PS3 after those title to cut the lost to minimal.
You will never know, like my case, I bought my PS3 solely for MGS4 and FF13, but now I have bought more than 10 PS3 titles. I'm not saying that you WILL spend a fortune on games, but I'm saying the urge will eventually come. Maybe you can borrow from you friends or rent, it'll be a great idea to expose yourself to some other genres and amazing titles with cutting-edge presentations (such as Uncharted 2, dante's inferno, GoW, KZ2, bayonetta etc); and not to mention playing blu-ray movies, which restrains you from spending another fortune on another player.
In terms of value (which I think you may be spending more than 100 hours on FF13, and another 100 hours on FFv13), durability (I'm looking at you, Xbox360), and functionality (online functionality, HD gaming and Movie), it's certainly worth to get your hands on a PS3 when the title is up, if without any delays, 43 days later.
I never regretted for owning a PS3 even I have had a gaming PC myself, it's a different experience despite its hardware limits compared to a gaming PC. Still it comprises a library of quality-standard games, which PC games have failed to achieve due to a bunch of indie developers that may technically turn a brilliant idea to an awry IP.
So that is what I think, may rationality drives your decision. Good luck =)
Thanks for the input.
Actually I bought my PS2 back in 2002 just because of the FFX bundled, but I was a student then. Now I have family with kids, so I really need a good reason to pursuade my wife since she and the kids are more into Wii
Anyway, usually English/International version will have some extra features so I'll wait for it instead of Japanese version. Hope that there will be FFXIII bundled pack sold then.
