This high quality steady cam HD video sums up pretty much everything ArenaNet is showing-off at GamesCom this year. Guess most other media will be just some variation of this. So I'm just gonna dump this one here for the lazy who ain't got the nerve to dig through the tons of shaky cam youtube footage. We might get a Direct Feed version somewhere down the line, which would be even more awesome; though this is likely as good as it gets. Enjoy!
 
  

Thats it.

I'm getting a new PC when I get back to Australia. 

After watching all of these gamescom videos I went from being slightly intrigued to full on hyped.

Dang - just got around to watching this in its entirety and it was way lamer than I expected. That dude just talked too much and showed too little. Hopefully there'll be a better 'comprehensive walkthrough' than this.

Eh, I appreciate that they put these comprehensive demos up to show to people who are unfamiliar with the game.

Dark_Lord_Spam found another 40min video which shows more gameplay and has less babbling. Some comprehensive Charr Warrior gameplay. Awesome.

Just a heads up - guildwars2live have just updated their youtube channel with a ton of 1080 / tripod gamescom footage, much pvp included.

Another version of the official developer walkthrough demo. Very high quality steady cam footage and a better speaker. Oddly enough, it starts out with an offscreen version of the GC11 trailer. They should have cut that out, but that's true for scores of the videos out of GC.
