* WhatCouldHaveBeen:
** ''Sammy vs. Capcom'' was in the works, and was rumoured to have been a ''VideoGame/{{Darkstalkers}} vs. GuiltyGear'' crossover, but has since been canceled.
** Also, Midway's Ed Boon [[http://www.videogamesblogger.com/2008/04/22/mortal-kombat-creator-ed-boon-video-interview-about-mortal-kombat-vs-ds-universe-and-street-fighter-vs-mortal-kombat.htm said]] that some of the rumours about ''MortalKombat vs. StreetFighter'' could have been true... if both Capcom or Midway decided who would have done the game. Midway's bankruptcy threw a wrench. Unfortunately, [[http://www.eventhubs.com/news/2011/feb/21/svensson-backed-mvc2-and-mvc3-because-fan-demand/ Capcom isn't exactly happy with the idea of Sub-Zero or Scorpion cutting Ryu or Ken's heads]].
** [[http://www.cubed3.com/news/15105 Ono]] stated that he would like to make a ''Nintendo X Capcom'' game.
** Developers for ''Marvel Vs. Capcom 3'' had wanted to put a number of cameos from ''Franchise/BreathOfFire'' in the game (Fou-lu from ''VideoGame/BreathOfFireIV'' was specifically mentioned) but this was eventually nixed as the ''Franchise/BreathOfFire'' series was seen as "too Japanese for a game aimed at Americans".
*** The planned appearances ''did'' eventually happen in the form of power-up cards for the "Heroes and Heralds" mode of ''Ultimate Marvel Vs. Capcom 3'', but to date ''Franchise/BreathOfFire'' is one of two known Capcom series (the other being ''Power Stone'') that have never made a full appearance in a "fighting" CapcomVsWhatever.
