I don't know what connection Capcom All Stars would have with Darkstalkers IV (pretty much none), but I do know that it would give Capcom a ton of slots per unused franchise. Are there people out there who really think that a game with characters from Darkstalkers, Red Earth, Onimusha, Dino Crisis, Project Justice, Mega Man, Devil May Cry, Breath of Fire, MvC2 (aka exclusives like Amingo and Ruby Heart), Dead Rising, Power Stone, Street Fighter, Resident Evil, Dragon's Dogma, Monster Hunter, Ace Attorney, Okami, God Hand, Asura's Wrath and Final Fight (the list just keeps going) would only sell 2 million? An all Capcom fighter with SFV style DLC support, day one crossplay and tournament support would blow MvC3 out of the water.
