The game announcement states that it "picks up where Monkey Island 2: LeChuck's Revenge left off". These two facts do not have to be mutually exclusive.

Especially considering that in the teaser video there is a character from MI3.

Murray is an awesome character. Though I often get him confused with Morte from Planescape: Torment (both sarcastic floating skull sidekicks).

I thought the implication from this trailer was that Ron Gilbert agreed to do this game if he could ignore the story and characters from the other games (which is why Murray is getting pushed off the deck)

It's amazing how many interpretations of this joke people appear to have :)

To me it's very clearly about Gilbert's past remarks that he'll never do another Monkey Island unless he fully owns the IP. Tossing Murray into the water means "yes, I don't own the IP and yet I'm making another Monkey Island, you can stop pointing it out".

Watching it again with that in mind, I think you're right. Now that I read other comments where he said that MI3 will still be canon.
