Virtua Fighter, NiGHTS characters in Sonic & Sega All-Stars Racing

Apparently, Sega's plan is to represent every Sega franchise ever in
Sonic & Sega All-Stars Racing -- except, of course, for
Segata Sanshiro. The publisher announced two more playable characters today (well,
four, actually, in pairs):
Virtua Fighter's Akira and Jacky, and
Bonanza Bros.' Mobo and Robo. The
Virtua guys appear to be riding in a red Ferrari, which would add the
OutRun franchise to the list as well. All these reveals are in line with the
character portraits found hidden on the website.
NiGHTS will appear in the game as well, though
not in a capacity that will cause superfans "DiGi" and "Trippy" to lose their bets and
burn their NiGHTS memorabilia collections. The androgynous dream-monster will appear as the
flagman in the racing game.
