i think its a new single player campaign. i guess it about the bit before halo 3. there was a massive gap between halo 2 and halo 3 this could show the brutes invading the earth which we didn't see in halo 3 and come to think about it the quote at the end "prepare to drop" could refer to master chief

hopefully they would make a new game more like call of duty 4 but in the future and not like halo 3.

either a flood invasion type play similar to the books the flood landing in the unsc drop pods or who knows what as the only recent halo news i heard was they where making a halo Universe fps with out master chief ( unsc vs covenant ) so who knows.

Hi i think thats just a trailer for normal Halo 3 (looks like the part of the game where the flood land in that city in Africa).

However, I have seen an article about Halo Wars which is going to be missions that you didnt seen in any of the games, however the Chief is not the main character.
