One thing I do hate is people saying "this is pre pre alpha so the game is going to look 100000X better!"
Yeah it's an early stage people...but game's don't magically improve in vast amounts. This is basically it...it's just smaller improvements from hereon out.

I need this in higher res and HD...

Try this,

Well that is very very very obvious when you see how stiff the people on the craft are moving you can tell it isn't CGI also the limited destructable enviroments is another clue (as opposed to teh destructable bridge). the clipping that occurs in the city when they are landing a third clue. The video does have some alpha look to it.

 lol, what about Halo 3? I've been fairly unimpressed by it (I'm just not impressed with the series anymore) but people swear it'll look 100% better than the Alpha stuff we've seen so far. 

I don't know about 100000000X better, but extra polish would make this even more stunning. 

Already said this Ben. I was a gametester before and am well aware of the stages games go through. Well unless tehy changed development techniques in the past 5 years.

There will defintiely be polish most likely in the variable effects but not much to the main architecture..Well unless a tester finds a way to warp through a level because of it.

Amazing. I was having doubts, but it truly does look impressive.
I'm interested in hearing more about how the weather is going to be utilized, definitely some potential there.

An issue or two (The way the "leaders" mouth moved seemed irregular, small complaint that will probably be cleaned up to say the least) that keeps it from the level of the pre-rendered video, but getting this close is definitely a great accomplishment.

 Thanks

damn!!
