BitSyncom said they shipped, and mentioned two of the recipients. He didn't say only two were shipped.
You're right. I don't think this will change anything until several people are posting pictures and screenshots.
For what it's worth, I think the attitude is going to be the same when other companies ship as well - people aren't going to be satisfied until end users are posting pictures and reports. And that's fair enough, really.
It has proven so in the past with Bitcoin Magazine, so it will likely continue to be so in the future.
