Whether or not they plan to bring her back in some way, I have no idea. But if they don't, then they have really screwed the series up for good. Even if they give him a replacement AI or give him a another copy of Cortana, it won't be her. Its pretty sad 343i had to kill off a major character to get people talkng about this game. Glad I only paid $27 for this crap. Thanks for screwing up a storyline I've loved for years 343i, YOU SUCK!!!!
