We tought the batlepasses were dalayed in the past because the some update was not ready.
Now they demonstrated once for all that they dont need a battle pass to end to release a major update. Neither do they need major updates is order to delay the battle pass. 
Heh
On the other hand, since the end of a BP is not linked to a major content drop, it’s better to have it prolonged to get some additional silvers and boosters rather than have nothing and just wait a week for a new BP.
I mean, it wouldn’t surprised me if they showed us a new map or maybe gold order stuff? Their messaging in the news update seems to hint there is content.
I hope that there is something new and i mean positive new stuff. I am really nerved that they are always extend the battlepass.
