From the ones U typed I will say:

Jade: She is not necesary. Probably dead, unknwon.
Tanya: I think she is ded. Unknown. Vey unpopular character.
Sonya
Frost
Kano (Possessed by Lui Kang): I think its been confirmed that that wont happen.
Rayden
Fujin: Not necesary. Not very popular.
Reiko (in form of Shao Kahn unless he was the one the alliance killed; I'm not sure.): Maybe.
Reptile (in form of Dragon King)
Li Mei (In form of Dragon King's Samurai.): That would be cool, to be able to fight as Li Mei but with the form of the dead army guy.
Johnny Cage
Jax
Kitana
Kung Lao
Bo Rai Cho: Not necesary.
Nightwolf: NOt necesary. Very unpopular.
Sindel: Maybe.
Smoke (in Robot Form)
Stryker: VERY VERY unpopular. NOT needed.
Ermac
Noob Saibot
Rain: Not needed.
Kai: Not needed.
Blaze
Drahmin (in his new form)
Kenshi
Cyrax
Mavado
Moloch: Maybe he is dead.
Sub-Zero
Nitara
Scorpion: He will be back.

Moloch isn't dead watch all the endings especially Rayden's. Granted Scorpion is probably is going to return, but I'm just saying he is dead don't get hopes up. I personally hope to see Reiko in the form of Shao Kahn in the game. He was by far my favorite MK4 character and it would be great to see. But your points are good I would highly doubt Ed Boon would put in unpopular characters such as Tonya. But it would be nice to see every Ninja.

Jade-vogel said they were working on her.
Kano (Possessed by Lui Kang)-I believe at fight night they said this wasn't going to come true.
Reiko (in form of Shao Kahn unless he was the one the alliance killed; I'm not sure.)He's not kahn.
Reptile (in form of Dragon King)
Sindel-died just before mk4
Ermac-kenshi freed him
Scorpion-favorite of boon, probably will return.

What do you mean Kenshi freed Ermac? And what do you mean Reiko's not Kahn? He put on his mask at the end of MK4.

Scorpion probably will return but hopefully better than he is in MKDA.

Man Drahmin is dead what his ending man he returns to Moloch in his previews form whith is HUMAN lol Moloch eats mortals so Moloch EATED DRAHMIN so - DRAHMIN IS DEAD yo

at fight night they said reiko is NOT kahn. that was a joke in MK4.

Kung Lao- Will most likely win MKDA.

Cyrax- Likely.
Sektor- In MK:TE, so likely.

Sheeva- Killed by Kahn.

Dude waht do people have against Stryker? I loved him I was good with him in MKT and MK3. Also, who is Sareena? I don't remember her at all.

Sareena was on MK:SF.

I think you mean MK: Mythologies UReiko. Her bio for MK:TE was posted on the main page, just search around for it there.

I dont think Sindel is dead. It never mentined that. Besides, Kitana is still call "Princess"...so, I dont think so.

She was killed in the MK4 intro comic that came with MK4.

The key word is "could." Anyone could be in mk6. No one know who is "offically" in the game. Who knows Kano COULD come back but that doesn't mean he is. It is the same with the dead people also. They COULD be ressurected, but that would be gay.

Exactly this is just the people that would make sense to return. I personally think it would be stupid to have dead people resurected. Granted some cool people have died, but them dieing helps push the story and new characters further. So in my opinion Scorpion should stay dead.
