The MVC 1.0 specification slated to be included in Java EE 8 continues to make progress and just released a second early draft review (EDR). You can download and take a look at the draft from the JCP site. You can also test drive the reference implementation Ozark from it's own site.
Community momentum behind MVC continues to grow as well. Most recently the Bulgarian Java User Group hosted a workshop on the specification via Adopt-a-JSR. The workshop was led by Nayden Gochev and Ivan St. Ivanov. All the details including starter instructions and code for the workshop can be found on the JUG's site.
There are many ways for you to get involved or just send feedback as always. You are always welcome to join the expert group proper via the JCP page for the specification. You can always simply join the discussion by subscribing to the MVC 1.0 specification user alias. If you would rather participate as a group through your JUG you can do that easily via Adopt-a-JSR.
