As shown in early footage, some characters had different names, color palettes and/or hairstyles. For example: The character Allen Snider had a different color palette (having blond hair and wearing a red gi with black, rather than the orange hair and purple gi of the final version) and he was originally called "Cashew Snider". Also, it looks like at one point they were going to use remixed music instead of new compositions, judging by the character select and Ryu themes.
