There is no info yet on ESL site, though I can already say that we will have a 5on5 tournament soon in ESL. After our small success with 1on1 Cup, ESL decided to give us more chances and more fun.
Possible maps for upcoming tournament (the format is not yet known, that's why there are few possibilities) :
It is probably going to be a 2 day cup (first rounds on Sunday, semi-finals and finals on Wednesday/Thursday).
To give you more info, I will have to contact ESL admins and simply wait. I created this topic to let you know already that we will have such kind of a tournament in upcoming days, so you can create your teams on ESL page and let your members in, for faster registration in the future.
GL & HF to all those who'd like to play a lil' bit of competitive side of 2D
