Commissioner Chester backing off of PARCC?

While these weekly updates are usually up online, the last few don't seem to be. I've uploaded this past week's here. 
In last week's Commissioner's update, Commissioner Chester gave some additional information about the new PARCC test to come. While there's some information about field testing (happening this coming spring), technology needs, and competency determination--MCAS will be required for graduation through the class of 2017--there's also this language, which I have not seen before:

Later this fall, the Board of Elementary and Secondary Education will discuss and vote on a transition plan with the understanding that, as the Governor and Commissioner have committed from the outset, the state will only adopt PARCC if it proves to be as good as or better than our current MCAS assessments.

emphasis mine
Interesting language coming from the Chair of PARCC's Governing Board
