Thanks Jeff. It's weird because the original press release stated it was available immediately. That copy seems to have gotten pulled.
Would love to hear a release date from the Marketo folks. Will this affect any code placed on pages? We are working on landing page updates not so it would be a perfect time to update any code.
Thanks for posting the link to the wait list, Jeff S!
Jeff C: we don't have a firm release date yet, but the implementations we're currently considering do not involve adding/changing code on your landing pages.
