So far it seems that Skarlet is a zoner, Geras is a grappler, Scorpion is a mid-screen and mobility character, and 16bit said that Sub-Zero is actually one of the best offensive characters in the game (so I suppose rush-down). Not sure about Baraka, Sonya, and Raiden yet.
16bit was talking about how running is gone, dashes don't go far, so emphasis is on walking. He said a lot of characters use weapons though, which means range on normals are higher. Most overheads and lows don't lead into combos.
Looks like they are trying to make the game have lots of footsies and neutral game.
