So Microsoft was holding their CES keynote last night and were streaming it online. When they started talking about Halo Reach, they also showed a trailer. However, they cut the stream off with this message when they showed the trailer.
So apparently Microsoft can't show off THEIR OWN FUCKING IP ON THEIR OWN STREAM! Get this, the trailer isn't even new. It's a trailer from last year however people not at the event didn't find that out until hours later.
