so i decided to buy a 360. Something i thought i would never do. well im going to buy one tomorrow but i already have aps3 im still a ps3 fanboy but im buying the 360 mainly for my friends (to play with them). So im planning to spend 350$ at the most and i want to know somethings. im thinking about the arcade so. how is it different then the pro or elit? different hardware and does it have a higher chance of RROD? did they fix the RROD? what is the warranty? so if i get it im going to need to buy a headset seperate, hdd, and whatelse (im gong to get mw2). Does the arcade suport hdmi? if i buy a hdd with a arcade will it be the same as the pro? how much estimate will cost ,e? srry for the long questions i just have low trust for the 360.
