So I've been flipping through the DC Adventures rulebook, and a lot of the terms are changing up: "feat" is now "advantage" for example... is this part of a move away from the OGL on the part of Green Ronin? Will future versions of Mutants and Masterminds not be OGL?
Oh, actually, Steve Kenson stated explicitly on RPGNet that yes, it will be.
The OGC portion of the M&M 3E rules can be found at http://www.d20herosrd.com/ (site working as of March 16, 2015). While this site may not be available in the future, the OGC license does not have an expiration date.
