Was there any difficulty in getting SF4 made?
Quite alot actually. Apparently most everyone at Capcom had given up on another SF game or specifically SF4 after SF3: Third Strike feeling that another SF would no longer be very viable due to the decline of the American arcade market and the overall decline of popularity in fighting games, but fan desire and the sales of Hyper SF2 on XBLA allowed Ono to convince his boss (Keiji Inafune) to put SF4 in production.
How long as SF4 been in production?
Keiji Inafune gave the project the greenlight in 2005, though it's unknown as to what aspects of the game's development started back in 2005, or if the game was given the green light to start production at a later point and time (2006-2007)
What platforms will SF4 be on?
Arcade, PS3, 360, and PC have been the only announced platforms at the moment.
Will there be a Wii version?
Currently there is no Wii version of the game in production, but that doesn't mean there never will be one. As it stands now the current version(s) of the game needs to be finished before Capcom can start properly downgrading a Wii version. In order to produce the best Wii version possible, it's better to wait and have a final build of the game in it's current state, rather then trying to port/downgrade a game that's still being worked on, tweaked, and touched up. It's also better that the current SFIV development team do the Wii port rather then outsourcing it to someone else, but in order to that the team first has to finish the version(s) already in development.
Is the game running on the same engine that powers Dead Rising, Lost Planet, Devil May Cry 4, and Resident Evil 5?
While a majority of Capcom’s new next-gen titles are being developed with the same engine, SF4 is being developed on the Taito Type X2 arcade board.
What is the storyline?
This is a rough translation of the story description on the SF4 flyer at AOU...
The year after the legendary World Warrior Championship (SF2) it silently begins. Suspicious incidents occur, and behind it a mystic organization is on the move in the shadows. Those chasing and being chased in the complicated middle of frienship and betrayal. Now, the curtain rises and a new fight begins.
When is SF4 set in the timeline?
Between SF2 and SF3.
If this game takes place between SF2 and SF3 then why call it SF4?
In the modern era of video games the numbering of a series is no longer defined by chronological order, and a number of developers feel that the gameplay is what should have a sequel and not necessarily the storyline. It's for this reason that games like Devil May Cry 3 and Metal Gear Solid 3 are given a numbered sequel instead of a prequel title, because the gameplay in #3 has evolved past that of #2 and that's what developers are trying to tell people with the title basically saying "We feel that this game is superior to the previous game's gameplay and a worthy successor" which is why game series like Resident Evil and Grand Theft Auto had so many titles between their third and fourth entries in those series, because the developers (Capcom and Rockstar) did not feel that any of those inbetweeners were worthy enough to be what they considered #4. With SF4 it follows a similar suit in that Capcom feels that Street Fighter 4 is the successor to Street Fighter 3 gameplay wise, and that's what the title is meant to imply, not where it takes place chronologicaly in the series, as in this day and age game series like Devil May Cry, Metal Gear Solid, Resident Evil, Grand Theft Auto, Castlevania, Samurai Shodown, Tenchu, and various others are not defined by chronological story progression when it comes to giving a game a title or number, but rather instead it's become more about gameplay evolution then story evolution. You also have to take into account those consumers who care nothing of the story in video games (which represent a large demographic) and want to know just from the title what the next big follow up in terms of gameplay is, rather then trying to figure out the chronolgy of a game series through non numbered games or titles that don't imply gameplay evolution.
How much of an impact do fans have on the game?
