According to the official Metroid Prime Hunters' website, Samus' next game for the DS will support Wi-Fi multiplayer. This gives Nintendo a good excuse for delaying the game until next year and brings the confirmed Wi-Fi game list up to four. No other details were given about how the multiplayer would work, but we'll keep you posted when something else pops up.

On a side note, the Metroid Hunters website has been updated with info on the 3 secret bounty hunters. Great new videos of all 6 characters were also added, and we suggest you watch them for your own pleasure.
The 3 new bounty hunters include Sylux, a mysterious creature bent on the destruction of the Galactic Federation; Trace, a parasitic being looking to find a new home for his race; Weavel, a ruthless space-pirate seeking revenge on Samus Aran for destroying his body.
