For now we did agree, I think in an MP Hangout, that there wouldn't be additional MP umbrella spec releases for 1.x unless the community spoke up wanting one.
For any specification that will be part of MP 2.x, there is a presumed base of CDI 2.0. However, that doesn't necessarily mean that a specification must use CDI 2.0 in defining it's APIs, etc. It's still possible to use CDI 1.2 within a specification if they choose, but being part of an MP 2.x umbrella release means that they will be executing in a CDI 2.0 environment.
