Congrats on getting another 360. I haven't had a lot of time recently to play with any of my systems, but when I have, it's been all about the 360. I don't even fire up my PS3 to play Blu Rays! I just find it laughable that the PS3 force screams RROD ... and yet, the 360 is still in the lead, massively - and the 360 is still selling.
I do agree with you on the flake factor on craigslist. Sometimes, folks get a better deal and bail.
As far as MGS 4 being the second coming? Please. Sure, it will move mad copies, but to state that as a main reason to get a PS3 is ludicrous. Buy a PS3 to play Blu Rays - or get one with Full or software BC ... but for MGS? Oh boy.
