It's here, as promised and a few days ahead of Christmas - Oracle WebLogic Server 12c (12.1.1) is available to download and is now listed on the official Java EE 6 Compatibility Page. That's now 12 Java EE 6 compatible configurations and counting...
For the developers among you, I'd suggest subscribing and navigating through Steve's blog (a product manager on the WebLogic team).
The formal documentation is here while the product data sheet is there. The top-level page for the product is to be found at oracle.com/weblogic.
The competitor in me can't help but notice that WebLogic beat JBoss to commercial Java EE 6 certification. Again.
