That I assume would be because PS3 works on a FAT32 file system itself and doesn't recognise NTFS - You can partition a Windows PC with a separate Linux partition and set it up with a dual boot menu - Linux will only take about 5 - 10GB for the OS as it's a tidy OS that actually packs all its crap away when you're done with it, unlike windoze
I've used Linux before, but only dabbled with it. I primarily use Windows because it's easy out of the box. Though if I ever get back into doing more things with computers that I used to love doing (a lot of song mixing and creation, beat makers and such) then I might go back to Linux.
Hey, here's a cool riddle...
What do you get when to combine Windows CE, Windows ME, and Windows NT?
Ever since I saw the Dragonborn trailer I am curious like others are, are we going to have full control over that dragon and more so can we fly every with it. I would like to buzz white run and scare the people with my flying suit case

So much speculation is out there, but only one thing is for sure.
Nobody on these thread except maybe you and a few others really cares at this point because none of us are going to be able to use this DLC. Just saying, speculation about what something is when you're not guaranteed the ability to even have it, is just going to piss some people off or at the very least, turn them off to you.
