As you said - the information is readily available and can even be viewed at this
Amazon link here (for free, so anyone with Prime can see it).
But, if you want a transcript...
Vice TV: The Incredible Hulk had stumbled, making less than Iron Man's box office, putting the MCU on uneven ground. To even things up, Feige and Marvel had a choice to make.
Zack Stentz (Thor screenwriter) : They had a board and it was like Thor, Iron Man 2, Captain America, and then like TBD movie, TBD movie. And then we came in one morning and we saw they had flipped Iron Man 2 and Thor.
[supplemental material: 'Thor gets a date in 2010'
Empire article link (released 2011, this is why I got confused with including Thor before - I thought I remembered that it played a role somehow]
Vice TV: Thor was considered a much bigger risk than the Hulk. At the same time, Iron Man 2 was in a position to set up the bigger MCU.
Todd McFarlane: If you build a strong foundation as they did with Iron Man, you can put a skyscrapper on a strongfoundation.
Vice TV: Iron Man 2 was now set to come out a year earlier than expected, sending the production into scramble mode.
[supplemental material: the only trace that I can find of the 2011 release date being flirted with is
this interview with Jon where he states 2010 or 2011 and
these comments in 2008 for the LA Times (which the article says there was a debacle with Jon and that he has now confirmed (in August) that it is set for 2010); which has it sound as though 2011 was discussed more during this time period (summer, 2008) as a possibility. Due to how many years ago these articles are - it's difficult to actually find articles to present here. If I was to
guess, behind the scenes Jon may have wanted 2011 whereas Marvel wanted 2010 that could explain discrepancies and the "debacle".]
Adam Chitwood (The Wrap writer): Immediately Jon Favreau was under the gun, and he's gotta get the sequel made, and the sequel has to be successful.
I guess it all comes down to whose side of the story one is more apt to believe - an "unauthorized" account
or an account by Vice TV that is authorized.
Adding: Marvel, Star Wars, Lord of the Rings, James Bond, Batman, and the Fast and the Furious franchises have all entrusted Vice TV with access to film clips and interviews with the filmmakers involved.
