I think they want to hang on to the cult fans and shippers yet at the same time they want a more mainstream audience. So they're outright lying-- feeding the shippers platitudes that they never intend to deliver on, knowing that the hardcore fans will hang on and keep watching out of hope and desperation, all the while they're taking the story in the completely opposite direction: mainstream romance and killing the co-dependant relationship. It's the only explanation I can see for the sheer magnitude of obliviousness to what actually happened in season 6 that we've gotten from Singer's interviews lately and now this Comic Con crap. It's intentional.
