Flash Player will be end-of-life at 2020

Adobe will stop updating and distributing the Flash Player at the end of 2020
Thats no surprise, we have seen trend in last years.

So what does it mean for the future of Heroes Online? Will Ubisoft switch to HTML5 or something? Or is this uneconomic and Ubisoft will stop of Heroes online?

Ubi: Please tell us! We want to know how long HO will stay alive!
