In the interview with Taylor Gray (VA of Ezra), he said that at the beginning Ezra also doesn't trust Ahsoka, because Ezra's the kind of boy not easy to trust anyone. Freddie Prinze Jr. also kind of added that Kanan will keep training Ezra, although Ezra will be more rebellious (puberty onset, probably).
Finally, Ashley Eckstein herself said that, in comparison with TCW, her role will be more like Yoda or Obi-Wan. Which means that Ahsoka will be the "wiser sage" role, but training will still be performed by Kanan (= Anakin in TCW).
Or, to summarize: TCW Ahsoka ==> SWR Ezra, TCW Anakin ==> SWR Kanan, TCW Obi-Wan ==> SWR Ahsoka.
I didn't see these interviews so that's why I made the prediction.
The one prediction I really want to see is Barriss returning as the Sith Inquisitor shown in the Season 2 trailer, the confrontation between her and Ahsoka after what happened in season 5 of TCW would be interesting to say the least.
