The BBC has a nice little article on Halo 2 with the usual kind of stuff in it-- will Halo 2 live up to expectations, what are the changes, etc etc. The interesting bits, though, come from Pete Parsons right at the end:

"We have several 100 years of Halo fiction laid out," said Mr Parsons.

and

"After Halo 2 we are planning to do something different. We will do something else and we have a few ideas."

Well, that certainly deals a little bit of a blow to those hoping to see Halo 3 debut on Xbox 2, doesn't it? Thanks Louis Wu at HBO for the heads-up on the article.
