At the moment it is just to early to say what will our implementation be.
Current state MVC spec & RI impl (Ozrak) are still in deep development mode and as such it is hard to tell what end impl will look like.
On end of the day when EE8 is out we will support also MVC 1.0 but how, that will be decided along the way.
Thank you, Tomaz.
Since this is still the number one hit on google when searching for MVC and Wildfly, I'd like to follow up:
Ozark has come quiet a long way and implemented most of it's features on the JAX-RS and CDI-APIs instead of hooking into jersey.
There is a RestEasy module that makes integrating with wildfly really easy: https://www.mvc-spec.org/ozark/docs/install-javaee.html
If you want to integrate even further, here is my take on a subsystem for wildfly 10. It will take care of activating MVC if it detects the @Controller annotation in your deployment archive: https://github.com/gtudan/wildfly-ozark
