You know, I was never really a big fighter fan back in the Snes days, though I did play a fair amount of MK but it was all just in good fun. Never played SF2 as much even though I had it, guess I loved the blood in MK as a kid and it just seemed funner to mess around in.
Anyways about SFIV, never planned to get it but it could happen. The fighter genre is dead to me but I've heard some stuff about SF4 that could make me like it. For instance it's supposedly more about skill and less about memorizing combos. That's the main reason I don't enjoy the genre, it seems like I just have to memorize random combos instead of just laying down some basic moves with awesome timing. I heard SF4 is more about the latter and you can easily beat someone that knows combos and moves if you have better skill and timing even with basic attacks. That would be cool and fun to me.
Actually I heard that SF doesn't even have scripted combos where you just press a random set of buttons and your char pulls of a chain of attacks, but instead it's just a combo counter that counts how many attacks and special attacks you pull off in a row. That sounds even more awesome.
