i used babelfish to translate it and i dont see anywhere where it sais that KOF 2000 will be brought to dreamcast, but maybe its in one of the pictures that arent translated cuz at the bottom of the page it sais "* The dream cast is corporation Sega registered trade mark. This commodity corporation Sega permitted use, it is the dream cast private software. "
sounds like wishful thinking to me since SNK isnt really around anymore, and the dreamcast isnt what you would call a profitable system, but i hope its true.
That second line in the top text image is "Dreamcast" (well, more like "dori-mukyasuto", but you get the idea) in katakana. Also, the banners at the bottom for Last Blade 2 and Garou (two relatively recent games that also happen to have DC ports) probably aren't a coincidence.
There are still SNK franchises going though. I read on a site that KOF2K2 is in development and whoever's doing it (Playmore?) are inviting ideas from the fans as to characters, backgrounds, all that kind of stuff. If this interests anyone I can go hunt down a link.
