So with Cetrion being confirmed as the daughter of Kronika and Shinnok's sister, there's more evidence that there will be hidden unlockable characters. The text leak that came out before the leaked image came out said that Shinnok was part of the base roster and Mileena and Shang were unlockables. Now we know that Shang is DLC, but all that means is he heard about him in the game and then just assumed he was one of the unlockables. Since the leaker is NOT the original source but someone who was leaked the info privately.
He also said that Cetrion was shinnok's sister and daughter of Kronika, which we now know is true. Everything the guy said so far as been almost basically right. (shang still in the game whether was unlockable or dlc) Highly likely that the secret unlockables will also be in the game. Now i still can't believe Shinnok would be in mk11, based off the fact that he's just a head in the background of a stage. Though that stage is also named after him, which happens usually with playable characters.
I also believe the secret unlockables would be the last characters they work on, which is why we don't see them in the testers screenshot. All the characters with no pictures and just letters have already been revealed, so likely none of them are story/krypt unlockables.
Everything is adding up to the MK11 roster page being 25 base + shao + shang + 2 "secret characters"
Also even if there was only just the 25 we know, i wouldn't be disappointed, mk11 is going to be great no matter what. It's still fun to speculate though.
You are right and the story leaks have been right so far. However, I think one of the leakers was mistaken. I think this was the situation:
Someone (or the leaker himself/herself) saw the base roster and some additional characters like Shang Tsung, Mileena and Shinnok. The leaker assumed they were unlockable.
But it turns out that Shang Tsung is DLC.
So I think these characters are probably DLC: Shang Tsung, Mileena and Shinnok.
Shao Kahn is a DLC pre-order character. He has been confirmed to play a role in story mode.
Shang Tsung, according to a story leak, is also supposed to play a role in story mode.
I think NRS is handling the whole "NPC fighters" better this time, by having them available as playable DLC characters.
I'm not sure if there's going to be unlockable characters in-game. But now I think these 'unlockable' characters are in fact, DLC characters.
Dear diary, its day number 372872 and people still think there will be unlockable characters in the game.
Edit: And the roster is 25 + Shao Kahn
No, it's 24 + Shao Kahn.
