Gunn is awesome, udude just keeps shutting the rumors (and Mayimbe) down with quickness.
Via his facebook:
All right. From this moment on I’m going to stop commenting on any rumors surrounding Guardians of the Galaxy Vol. 2, because, eventually, someone is going to come up with a spoiler that has some truth to it. That said, the rumors surrounding Quill’s parentage at the present moment are completely false, and aren’t even close to the truth. I don’t know how people come up with this stuff, but it certainly isn’t through legitimate sources.
Also, I get the desire to get “scoops” on character inclusion and casting choices, etc. But since when is a plot spoiler a “scoop”? Is this really what fandom wants to know? Plot details in movies ahead of time? I got in this business because I love movies, and I think most film journalists are the same way. And spoiling plot details doesn’t add to the enjoyment of the film-going experience. So bravo to those folks out there who don’t partake in this sort of thing.
But, as I said, eventually someone will actually spoil some detail of Guardians of the Galaxy Vol. 2. So this will be my last comment squelching a rumor until May 2017. But if you do pick up on some plot detail between now and then, be aware, A) They are likely full of ****, as has been everyone so far who has claimed to have had inside info, and B) We’re creating a film that doesn’t rely on plot twists to be an enjoyable experience. They’re only a very small part of what we’re cooking up for you.
