I just got a GDC email that listed some Wii titles that SNK will be showing off. We finally have another confirmation of SNK Arcade Classics: Vol. 1 for Wii, and we also see that they have some other games lined up.
SNK Arcade Classics: Vol. 1 (PS2, PSP, Wii)
Samurai Shodown Anthology (PS2, PSP, Wii)
The King of Fighters Collection: The Orochi Saga (PS2, PSP, Wii)
Nicky Hill, Cort, and myself are all going to GDC, and we should be able to get some hands-on time with these titles.
