I have that for the 3DS, forgot to mention it.
So you don't really have it so, SSFIV is an entirely different game on console due to the wider range of controls and increased precision, plus the arcade edition DLC is upcoming which will change the game's dynamics a fair bit.
I don't have time to type out a long post right now, like I normally would but I would suggest you think about what kind of type of fighting game you want. Some have sharp learning curves, some are more reflex based, while others require meta-game knowledge and good combo learning skills. Would also suggest you get at least a fightpad, if not a cheap stick if you intend to take fighting games beyond casual play at all.
