It's on NetFlix... a web series, but I might check it out, but seems pretty cool while we wait. Ever since the movie got cancelled (Peter Jackson was set to direct- Can you say "Epic" in your best Master Chief voice?).
Halo is running the risk of ending up like Final Fantasy- AKA- Another dead horse for the gaming world. Seriously, there must be 20+ FF games out there (although they call the latest 13, there are many more than that). I get it, Halo is popular, the concept is fantastic, but seriously, go too far and you run the risk of losing originality- I hope the next gen does it right and keeps it fresh... They could learn from one of my favorite series, the Elder Scrolls, they're gearing up for ES-Online, and I hope that they make a 6th game in the series, the mod community for Morrowind (the 3rd game in the series) is still going strong after 11 years. That's doing it right.
