TBH we'll only have an idea of the answer to that when we actually GET USF4. Red Focus and Double Ultra have the potential to significantly change the game, so if the game gets a new lease of life... maybe. Of course that's a very big "If" - SF4 is about as big as it'll get, I'd say. It had the advantage of being a big blast of nostalgia for the SF2 characters - a lot of non-fans I introduced to the game were familiar with them and were like "Oh yeah, that guy! Stretchy dude! And electric green guy! And sumo dude!". The Alpha and 3rd Strike characters didn't get any of that, judging by my experience. So nostalgia for SF2 has been used up, and nostalgia for Alpha and 3s doesn't really have as much pull. So SF5 will actually have a relatively hard time - I'd say the next time Capcom hits it big with a SF game is when people start getting nostalgic for SF4, which is why they've said that we won't see SF5 until at least 2018.
