Gives me hope. Also i think this is the only thing that Blizzard said about their new MMO.

EDIT: Looks like this was posted under a video already

I just hope it doesn't look like a Wii game like Diablo 3.

 I hope it's good. Knowing blizzard this will come out 2012, after we all die, and after diablo 3 is released. I hope its a MMO FPS. I have faith Blizz can develop amazing games. Here's hoping for this one.

No matter what it is I have a hard time believing it can trump Wow itself.

I tend to dislike Fps mmos. I find them way too stressful. If I want to shoot things, generally its not an MMO i'm looking for!

So now I know that it will be a SciFi Fantasy FPS MMO, well this is interesting.  It is completely new and built from the ground up as well, and not an already established IP.
