IMdB is user based, similar to Wiki, so keep that in mind. Also - it looks like the original post has been deleted. I got this via CBM.
I'll post my comments in bold next to each description.
Who knows if it's true. Doesn't hurt to go with it for now.
Agent Coulson does NOT die as some previous rumors claimed (He's not a Skrull either). - There was mention of Coulson on twitter as a skrull with Clark Gregg jokingly mentioning it a possibility.
Captain America's new suit looks amazing from what I or my friend have seen/heard :P. Similar to his costume in Captain America: TFA but the gray straps on his upper torso are gone, the blue is a darker yet more vibrant blue, the star on his chest is bigger, and the red stripes on his abdomen area are actual stripes on the costume and not part of the straps. It also looks less like hockey pads and more like a sleek costume. Very Avengers worthy. - A new costume makes sense as the one we see in Captain America: First Avenger is set in the past, plus a new team suit would be just right.
Thor does not return to Earth until roughly the half way mark. We have scenes showing him in Asgard before this however. - Makes sense as we saw in Thor, Thor destroyed the Rainbow Bridge, that which connects Asgard to Midgard (Earth). It was stated Jane Foster was looking for a way to find Thor. We know Natalie Portman is in Avengers, so assume she finds a way.
Ruffalo's Banner is very much a scientist and geek from what I've seen. He surpasses Norton 100 times over IMO. - Good news to me as I didn't think much of Norton.
I/my friend have yet to see Renner as Hawkeye but I think his appearance is going to be similar to Scarlett's in Iron Man 2 in regards to screen time. - Yeah, most likely not much as there are just too many big names and characters in this film.
This is one I'd like to clear up, NO ANT-MAN OR WASP. As of right now they are NOT in the film unless they're put in later as a cameo/mention. - Again, too many characters. This won't bother me if they don't show.
That I know of, there are 2 references/Easter Eggs to other characters, Black Panther, and Vision. From what I've fathered I think they're alluding to Tony Stark being the creator or at least part of a team that creates Vision but DON'T quote me on that one. - I could see reference to Black Panther as Marvel likes to push that character A LOT. Also Tony helping to create Vision or even Ultron makes sense.
Throughout the movie the team wont really have one specific leader, it's going to be a lot of pushing and pulling for the top spot because in each members eyes, they are the most qualified and they're not interested in following. - Sounds about right as everyone will be butting heads initially. Who they kidding? Cap leads.
Lastly, the movies villain(s). Sorry to disappoint folks but no, the Skrulls are not the villain(s). I wont reveal who other than Loki plays a villainous role because it's just too good of a plot point to spoiler for you guys. The Skrulls will be mentioned/alluded to, possibly for a sequel? It's possible. - Well, there are lots of aliens in the Marvel Universe. The Kree have already been mentioned for "The Avengers."
