The sucess of the PS3 depends alot on the marketing of Sony. They have released so many different statements saying what it will and wont come with, what it will and wont support etc, its like a guessing game for the customers. If they release it with at least what 360 came with (hard drive, internet access) then it will be big, however they need something massive to beat Microsofts sales because of the stupidly late release date.
Oh and the controllers are HORRIBLE!! lol
I have a 360 and it's ok, but the PS3 should blow it out of the water...only time will tell...
