Is this vaporware?

Not really vaporware, you can pre-buy it on Sony's website in France for 799€, it will be delivered free of charge in mid-december :

And yes, you're a bit late in the party, there are already multiple threads about this HMD on the MTBS3D forum.

There is discussion over here: http://www.mtbs3d.com/phpBB/viewtopic.php?f=120&t=13674" onclick="window.open(this.href);return false;
