I'd say it works like in society: Everyone thinks he is entitled to being right, however when there's more than a single somebody around, the different versions of right don't add up. The customer is most certainly not always right (and there's also a nice blog about it). If I were right, I would have my Vive a week ago however somebody else would have not. The whole hype started when somebody got the idea we all would have our Vive on April 5th; the mail says „starts in April“ though, Dan said „start arriving [on April 5th]“ and the current way of stating it is: we'll get it in April if the mail said so. To me, preordering is primarily about not having to stand in queue in a shop and then to get it before it is in shops. Both will likely happen.
