You can read what they have said so far either in the Dev Corner or here.

I heard katarina was going to get a rework? why not make her running figure look more assassin instead of power walk? whats new?!

if they do rework her i hope they remove her 750 base damage on her ult. it already has a 1.3/1.2 (I cant remember) ap scaling on it

No, it's not a rework. It's a roster update, like they did for ADCs and mages.
