Ok here's a brief summary of the recent events:
Palmer has been nearly silent since the launch. The Oculus twitter account has tweeted nothing but retweets of press reviews and shit. Pre-orders have finally started shipping yesterday and today, but the units shipped are up to those that ordered in the first minute (and not even all of them).
There are two anonymous Reddit posters making claims. One of them is saying the manufacturer put the wrong lenses in the headsets, rendering the entire stockpile unshippable. There is an issue with the lenses of the early KS headsets that were shipped, but I don't believe this guy.
The other Redditor is claiming there is an issue with a "partner", likely the payment processing company. I kind of believe this guy because he has made multiple predictions (claimed as fact) before things happen, and they've been very accurate.
[EDIT] To clarify, the fresnel lenses on the earliest CV1 units have a "glare" effect that is a known problem with fresnel lenses. It's unknown if the later-shipped Rifts have this issue or not. If they do, it invalidates the guy's claims.
[EDIT2] Oh! And the Rifts were supposed to ship with multiple faceplates to better accommodate glasses-wearers. It only comes with 1. I don't necessarily think this was a mess-up, but more likely a decision that was made and never communicated.
