What does Bungie need to do to freshen up Halo with Reach?

[The Anarchyz]

I think Bungie already knows how to make a good Halo game, and if the pull of a great single player this title will be amazing...

But personally, i'm sick of Bungie dedicating themselves only to Halo titles, i want a different IP from them, i don't see one since the Marathon, Myth and Oni days...
