So I'm mildly interested in this game even though it made me angry last time through (or rather the people who were annoying with the Ken/Ryu clones made me angry).  I sold my old copy but I kept my SFIV controller since Gamestop was going to give me less than $1 for it thinking I would just later sell it to someone but never got around to it.

I figure the thing that can push me over the edge is if I had all characters a bunch of challenges unlocked in SFIV, will those things still be unlocked in SSIV or will I have to go through and unlock them all again?

So far i know I didn't read anything about it.

We will probably will hear it when reviews come in...btw GT has a preview of SSF IV maybe they say something about it;

Just watched the preview, that's what made it fresh on my mind again. 

-edit-

Just in case other people are curious

Well that's upsetting, getting some of the last few characters was kind of a bitch.

Thats like getting a hooker and then coming again next week and asking if her twin sister, who is also a hooker, remembers how you "like it".

Not likely.

Wow, you guys are really out of the loop. One of the first things confirmed about SSFIV last year was that all the characters will be available without having to unlock them. Although gamers that kept their original copy of SFIV are supposed to get some sort of bonus.
