I think Bungie should be bitter. Imagine building something from the ground up, and making it a huge success. Then, some other developer comes on over and just builds off the work you already did, making a ton of money on it, not to mention the ridiculous and stupid things they did with game. After the leaked info everyone already knows about, I wont be buying the game now, I was okay with everything until they showed you know what. Thats a line you just can't cross.
