I will say that 2 of your points are not relevant but the others are critical.
Roster size... it's better to have a good and varied rooster than to have only numbers... Capcom or another dev said that they saw too many chars that played the same... I think that was the reason for roster size on SF VI. And going by what was said during Killer Instinct, most players use a couple chars only.
On the recurrent releases...
Forza, CoD, Sports Games and several others have yearly releases with cosmetically changes and it sell well.. Capcom prefers to keep the game base, release DLC for new chars/clothes and at the same time re-release the game with the DLC. Similar practice, but on this you have the option to only buy the DLC or not even buy it and keep playing base version, I kinda prefer it.
