The tweet translates to: "On this "Tuesday of Halo" we remember the xbox E3 of 2003 and 2004 where we learned more information about the legendary Halo 2."
TC's quotes are referring to the 2003 and 2004 E3 presentations, respectively.
How exactly does this tease the anniversary edition?
Well you could say that because they're referencing it, that means something new about it will come out. Or, they could just be referencing the game 10/11 years ago which iirc was the largest media release ever at the time. That's much more likely.
