Some of the names of the characters in Street Fighter Series entitled Sagat are Sagat, the Street Fighter himself who was born in Thailand. Some of the characters are Abel, Cody, Guy, Blanka, Dudley, Hugo and many more.
Super Street Fighter 4 is basically the same game as Street Fighter 4. SSF4 features everything SF4 had, with more modes, moves, and characters. Super Street 4 will tweak some minor things, but by no means is this a different game than Street Fighter 4.

No, they are completely different stories, characters and graphics as well, they are no where like each other. This and: Dragonball is older than street fighter by quite a bit.

Yes, i think so but i don't think not now, the only people that are already in that is Tekken Fighters: Kazuya, Nina, king, Craig marduk, bob, Julia, and hwoarang Street Fighter Fighters: Ryu, Chun- li, ken, guile, abel, cammy and sagat. these are the only confirming characters in the Street Fighter X Tekken. However, there are 14 characters in all so far.
There is a patch called Street Fighter X Tekken 1.06 that one can download to unlock other characters. Run the setup program and install it and copy the file, const.lua under the StreetFighter boot game folder.
