Halo 4 Trailer... WTF!?

Halo 3 had one of the best endings in video game history. Finally giving Master Chief the send off he deserved; a hero floating in the midst of space, saving humanity and asking Cortana to wake him if she gets lonely. I mean that ending impacted me emotionally because I got to care for Chief and Cortana over the course of three games. And when it had 117 carved into the piece of ship at the memorial, I shed a tear because of how masterfully it was done. And at the end, the very end, he goes back into the cyrotube, ending it just as it began. Then, 4 years later, they just had to show that ridiculous Halo 4 trailer. I mean seriously, Microsoft just ruined one of the best game series of all. I'm glad it's not made by Bungie but it's their fault for putting that awful Legendary ending. I mean... I just can't believe it. It's like Tugg Speedman in Tropic Thunder.
