If the YouTube video isn't good enough (720p?!), there is a 1080p video on Fileplanet... but it is 1.8GB lol.
Here's a link
BF3 12min Faultline Trailer 1080p.
I really cant wait for this game, I'm torn between buying it for my PC (Will need a new GPU, 8800GTS just won't cut it anymore!) or for my xbox so I can play it with my friends on there. The option I'm considering most is just buying it for both though!
They haven't released any full system specs as of yet however from what the developers have said it will only be on Vista/7, so no DX9 support, it may even have a 64bit option so it can use more than 2GB RAM and you will generally want a quadcore CPU at around 3GHz.
Anyways, I'm going back to playing BFBC2 as I still have some achievements and insignias to get!
