The flying element is demontrated here in the the third video. Also, scroll down to the fourth video to see what I believe is called "vertical cover":

Bottom line. Obviously, it all boils down to fun and how responsive the controls are.
A multi-player element would just complete the package for me and some users in the
Dark Void forum are expressing similar sentiments. I guess If they don't add online
multi-player then they should at least support some sort of network co-op mode.

Based on how well RE:5 is expected to sell + SFIV + SF:hdr Capcom, I would imagine,
is gonna rake in enough money that they don't really have to rush Dark Void out the door.
Why not polish the game and add some multi-player component to what already seems to
be a solid foundation?

Shana T. Bryant add multi-player to Dark Void! I am talking to you woman to woman.

I'm really anticipating this game. The only thing that concerns me is that Dark Void, reportedly, doesn't have any online multi-player component. The flying mechanic in Dark Void also holds potential if it is cleverly implemented on the Wii. Assuming Capcom eventually decides to make a Wii version.

Only the lack of online play causes me concern. Other than that, looks good. 2009 is shaping up nicely for the house or Ryu.
Shoryuken!
