I've recently seen footage for the Halo 3 beta(unless you count that leak on game trailers a couple of weeks ago), and I have to say it looks a lot like the first two games.  However, im not entirely sure that is a bad thing now is it.  If they put down too much changes than they would lose many of their hardcore fans(definition of hardcore is if you play it 2 hours a night).  Another thing is the graphics.  I mean it looks good, but not Gears of War good.  Now I know this is a beta, but I am just giving my initial impressions.  I am extremely excited about the new features like the mancannon, the spartan laser, and the deployable equipment.  I am looking forward to driving my warthog on the mancannon and getting hit by a rocket launcher while in midair.  I am just give my feedback on the whole thing.  In fact I have a thoery about this beta.  I think Microsoft put it out this early so they could get feedback to see where they need to improve their game by the time it is released.  All this aside I still am looking forward to it and im sure that it will not dissapoint.  Halo will live forever.
