For the ones coming out after my birthday, I hope a friend or my family preorders them for me
I'm waiting on Square to announce a PC version. It's already largely PC ready due to the method of creation, all it needs is optimization and assorted added options, like with the Last Remnant.
Also, technically the console ports are being released first anyway :P (Yes, they're ports. Squeenix uses a PC-based coding and creation method that is then ported to code the consoles can interpret and use).
I don't have an HDTV so that defeats the majority of the purpose for getting a PS3. I also do plan on getting more than just FF13 and I like the 360's selection of titles better.
Better game selection and my 360 has never RROD'd and I've had it since '07.
