Marvel Realm of Champions | NYCC Announcement Trailer

I just heard about Kabaam's upcoming game "Marvel Realm of Champions". The trailer is below. It looks...interesting. I'm not really sure what to think about it. I love Kabaam's other games "Marvel's Contest of Champions" and "Transformers: Forged to Fight" and I hope these won't be examined. So far the biggest questions I have are: Will it be "free-to-play"? Will I be able to use my KAabaam account across devices? And will it play on my iPad? Contest of Champions does, but Transformers does not because my iPad is too old.  Guess I will find out some time in 2020.
