To be fair what did you expect Gunn to say? It's not like he'd admit it even if it was true.
And in most cases they can't confirm their sources. It's not like they could've said "John Smith at Marvel told me Thanos is confirmed for 'The Avengers'". They ain't trying to get people fired.
I'm not saying their info is 100% correct but they've been right often enough to pay it some mind.
Fred.
but Gunn wouldn't flat out deny it either...
And I'm not saying they have to reveal a source, but if they're being fed this info, they need to confirm those facts with multiple people that what their source is telling them is true before they report it. That's just how reporting works. Otherwise you're just writing what random a$$holes tell you.
Remember, this is coming from a column on LR that reads like a comic book version of a gossip blog and the writer felt the need to reiterate this disclaimer before this post:
IF THIS IS YOUR FIRST TIME HERE: Welcome! This is my weekly column where I talk about superhero movie news, rumors and speculation.

So anything he gets right he can claim as insider info & anything wrong he can play off as rumor or his extrapolating & guessing off scraps of info. That's why this kind of reporting where opinion, conjecture & guesswork is in the same paragraph as factual information becomes so murky. The phrases like " stlll think..." and "I'm so vague on what happens...so let's just say..." don't have place next to what you're telling us is inside information.
The people picking this report apart use an example of Feige stating publicly at the Phase 3 that there are no plans for Black Widow or Hulk stand-alones through the end of Phase 3 but they're main parts of all Avengers movies announced so far while this report has them missing from IW1.
