The concept art of Jax that Blitz4560 mentioned (skip to around 3:05): https://www.youtube.com/watch?v=fdt4JWuq6Ns

Above I posted a link to a leaked cut-scene picture featuring Jax, Johnny, and Sonya. Jax in the cutscene has the same design as in the concept art.

Recently, a roster leak happened that contained Jax, Johnny, Sonya, and Kenshi. So... they are all most likely playable.

Also, Jax's boot in the concept are matches boot 5 (I think it's that one) on the Boot Teaser that Ed Boon posted months ago.
