I mean really.
Not only will there be enough game releases to help you decide which system you wanna purchase (Assuming you're gonna buy one or will buy only one.)... But people will get to know the consoles for real, and decide what's right, and what's wrong.
I mean, look at pre-release X360 and PS3. And look at after their releases.
Heck ...A better example, look at the Xbox One from half a year ago, and look at it from 3 months ago ...Almost 2 different consoles.
How about you? Are you trusting enough of these companies to buy one in it's first year like that?
