I always liked SNK characters more than Capcom's. Since the release of SF3 I think I only liked about 4 of the new characters that Capcom has introduced since then.
To be fair, save for Team Japan and Team USA , no country was being represented by actual people of that nationality, the story said they were just assigned countries to represent for reasons not explained, most likely to make it more of a global event.
What i would want:
Ramon -> Jesús Barrero (Seiya from Saint Seiya)
Angel -> Christine Byrd (Sakura from naruto, Helga from Hey Arnold)
Tizoc -> Sebastián Llapur (Has great range, but no iconic roles)
What we would prolly get:
Ramon -> Mario Castañeda (Goku)
Angel -> Isabel Martiñón (Marceline in adventure time)
Tizoc -> Beto Belez (Golden age Homer)
