Google and Symantec settled on this. Symantec will create new certificate roots which will be cross-signed by both their existing roots and another certificate authority. This allows the trust in the existing roots to be removed in the long term and it has significantly less impact for current Symantec customers than the original proposal.

I am also interested in this. This whole process has been a shitshow. I'd just like a decision to be made and a little warning so that I have time to replace my RapidSSL certs (they are signed by GeoTrust which is owned by Symantec).
