BLITZ TOURNAMENT

and now, the main question (in this post): are there still plans for 5 stages? or can we hope for something better?

Yes, there will be five stages, followed by a break of approximately one month.
And in August, we will hold a full-fledged tournament. It will be, so to speak, a warm-up before the eighth stage of Van Kanegem...
And on September 1st, the eighth stage of Van Kanegem will start; it will be dedicated to Heroes 3.

So, this is the official tournament schedule for offline Heroes 3 tournaments for the near future.

Sincerely.

to AmberSoler: and how did you manage to answer faster than me... :D
