You really didn't need to separate the two threads that you made. Besides, there are plenty of other threads about this topic. Use the Search feature next time, please.

Reptile, Smoke, Noob Saibot, and Rain.

God damn. Where is the moderation on this board? Someone just make a topic called, "Characters Old and New that you would like to see return for future Mortal Kombats!" and sticky it.

Imagine how many new threads there will be when the first bit of information is leaked. They will release 4 new characters, and then one returning and then there will be all these topics asking, "Since Kung Lao is returning, do you think that Smoke has a chance of returning? Hopefully he comes back as a ninja!"

Can't wait...

Anyway, no classic characters should return. Not Liu Kang, not Sonya, not Scorpion, not Reptile, none of them. Only character in the entire series I would care to come back is Kenshi, and he's not even my favorite character. He's just a badass.
