I agree, so far I have herd that these characters are unlockables.
Note: I think this is BS
Kintaro
Goro
Monster (maybe)
Onanga (maybe)
Sonya
Johnny Cage
Akuma
Shang Tusung
Quan Chi
Ghost (Maybe)

Akuma....WTF!, i have heard so many rumours but none of the have been confirmed

Ya really I've never heard anything about Akuma in MK You mind 'splaining that to us?
I agree that we should to to get a hold of him cause this is getting annoying with all these rumors and speculation going around, I personally think they are all lies but my true nature can't rule anything out...

Anyone that was around last game knows what a crazy rumor mill this is. At least this time we have a knonquest full of possiblilites to be wrong about. Last time it was just sad watching people come up with the most insane things they could think of to try and prove that stuff existed that didn't exist.
In the end all the crazy talk is to Midways advantage. It keeps people playing it , talking about it, and more people buying it hoping something else will soon be found. They have no reason to want to tell us anything at this point.

Ed Boon did confirm the super unlockables in the August issue of gamepro.

Yeah, but he also confirmed the final secret for MKDA, too.
Anyway, why would they realese the Super Unlockables right now? The game has been out for a friggin' week.

He didn't actually confirm the final secret for MK:DA, he said "as far as I know there is one secret nobody has found yet" and he did say that it wasn't a secret character. It's not confirmation as he didn't say "there is one secret nobody found", but then again it is a good hint that there really is something else. Also I believe it's been said that there is some code to see the MK:DA version or whatever and that is the final secret. I know, it's a crap secret.

Yeah, I know. Axeman61 said one of the devs told him that put in a button code, and you'd see your version code.
