Definitely sounds more like the Ultimate version of Ronan we're getting....i.e., evil son of even more evil Emperor goes out and slaughters Drax's family (or worse); Drax has a personal vendetta against Ronan; then takes it out on the whole Thanosian Empire.
And I think the circumstantial evidence is piling up big time that Yondu is really Quill's father. The Star-Lord crest, Rooker's comments at SDCC, the fact that Yondu is the only listed "known associate" of Quill on his Nova Corps rap sheet....I think the way it all shakes out is that Quill's mom was one of Pirate Yondu's many interplanetary bedmates and Pete is his bastard son; then, for some important reason or other, Yondu returns for him later in life and takes him under his wing. Quill becomes a chip off the old block and loves his space pirating career, but around the end of Reel One, Nova Corps catches up to Yondu & Son's pirate ship at long last, and Daddy skedaddles and abandons his bastard son to the cops. Quill goes to prison where he meets the rest of the Guardians, and the rest is history. Hell, there might even be some fanservice going on there with Yondu being an original Guardian of the Galaxy before he took off on his solo career, and Quill adopting the name when he assembles Drax, Gamora, Rocket and Groot for his own crew.
