Yes, you don't know me or my brother, so you can choose to disregard his informed opinion if you like. Yes, some journalists rush stories, or aren't quite knowledgeable as they should be, so you can choose to disregard what those journalists say. You can even believe that the end consumer product may not be as good as what was shown at the GDC. That's your belief.
The "morons" who have prepaid for it have read the opinions of people of many people that have experienced the product. They're basing their pre-purchase on the fact that all people who have tried it, have approved of it. This is an informed purchase. They're paying $400 for a product that has excellent reviews. Your take is basically "don't trust them, don't trust the thousands of people that have tried it, don't trust anyone but yourself". Basically, the cynical point of view.
I think it _very_ unlikely that Sony would take a product demonstrated to thousands of developers, and god knows how many journalists, and make it worse. But you know what, if you think they may do so, that's fine. I'm not actually trying to convince you to preorder the thing. I'm just trying to say that calling everyone who preorders it a moron, is a pretty awful thing to do, and even worse, is not even right. If it was ordered totally blind, you may have a leg to stand on. But the headset has been experienced by so many people, so many! The majority, or even unanimous, consensus is that it's the real deal. Based on that, a preorder is quite understandable.
Laugh if you will. Those that preorder this are happy with their decision. Please try to respect that and not insult them.
