Jamon,
It's not whether or not TIH is in continuity or not, because technically it is. But, for anyone who saw the recasting of Banner as sort of Marvel's acknowledgment that they're discarding TIH, name checking Banner in Thor is basically his first introduction in the Marvel Cinematic Universe....
Recasting Banner isn't the same thing as recasting Rhodey.
Basically, you can accept TIH like most fans have or you can ignore it and choose this film and the Avengers as his proper introduction, because of the recasting.
Personally, I don't like the film so having Selvig name check him was perfect.
For my money, the Marvel Cinematic Universe goes Captain America The First Avenger (if it works as a film), Iron Man, and Thor...leading to the Avengers. And yes, I left out Iron Man 2 for a reason.
