I heard from somewhere that the Metal Gear Solid series may be moving over to the 360, so that will hopefully lose a lot of Playstation fans. I like both the 360 (Gears of motherf*cking War) and the Wii, but the only console I generally don't like is the Playstation. They can lick my nuts.
I read that too, I forgot the name of the company that made MGS, but it is so expensive to make that they will have to port it to the 360. Anways, I'll go with the 360: better online service (even though you pay, but it's less than the price of one game a year), awesome exclusives (Halo, Gears, Halo Wars, Banjo, Lost Planet, Lost Odyssey, Mass Effect, Too Human, just to name a few), ability to transfer saves to your computer, the new 100 gb harddrive (which is said to be a rumor, but I think it was confirmed), and much more.
