Looking at these two pages (
CHMP eligibility and
tier list), we can see that Championship registration is only open for pre-qualified teams (23 teams) and teams who are in tiers 3-8.
I assume that the 23 pre-qualified teams will sign up shortly. As for the tier 3-8 teams, it is hard to tell. Tier 4,5,6,7,8 teams obviously do not place a priority on attending the Championships, since, none of them have been for many years. Most likely, more tier 3 teams will sign up within a few days, but not too many.
I am guessing that maybe 35-40 teams will eventually sign up out of these groups. Currently, there are 11. The 20-30 teams out of these who have not signed up probably just assumed that Championship signups were the same day as 2nd regional signups, which are 10/28.
I wonder when tier 2 will open up for registration to the Championships. Any guesses? Once tier 2 opens up, many teams will register. There are over 300 teams in tier 2.
