Even the Nova Corps rumors *are* strange. There's no mention of an actual, you know, Nova yet (as either Rich *or* Sam), and as for Rhomann Dey? Yeah, that's great that they're talking about the Nova Corps' own version of Abin Sur, which certainly paves the way for our Richard Rider or Sam Alexander; but then the rumor gets totally wonky by describing Rhomann Dey (an alien) as a *human* liaison between the Guardians and SHIELD. SHIELD??? lolwut
I have seen some descriptions refer to the Guardians as fugitives/ex-cons. Its not that wonky to have space cops involved, nor that strange that they held back using the premiere Nova character in terms of popularity. Who knows what plans they have for him? Even if they don't. they might still keep their options open rather than pull off a situation like X-Men that seems like it might end up with more than one Trask.
The rumormill has gone totally off the tracks from an actual Guardians of the Galaxy story. The rumormongers are introducing all kinds of extraneous characters that sound like fun for the greater cosmic Marvel as a whole, but every single mention steals more and more of the spotlight from our title characters.
I don't understand where you are coming to this conclusion. GotG takes place in space. Unless Gunn was going to make a version of Sunshine where it is just the Guardains together on a ship there was going to be other characters populating the world for the GotG to interact with.
Again, it just makes *more* sense to believe that most of these new casting rumors, if there's any credibility there, would tend to point towards characters who make sense in the context of the Guardians of the Galaxy, and Thanos, who is clearly the GOTG nemesis. *If* the rumors turn out to be true, then Gunn has put together a kitchen-sink all-over-the-place mishmash of Cosmic Marvel that doesn't seem to have any cohesion whatsoever.
Yes, the rumors are just rumors, but so far not a single rumor is that outlandish or left field for me to think that it is an out right lie or wrong. Improbable maybe. Surely surprising. But definitely not impossible.
I think it is unfair to assume Gunn is just throwing characters together without a plot. You can't use the casting rumors to guess cohesion
