As you all know, Epic Games is already before release of patch 10.40.1. This patch is one of the last of Season X, which means it may hold a lot of info on the coming Season. So far, nothing of value has been discovered except for the ending period of Season X. Season X Is bound to end on October 17, if the discovered placeholder is not a trick by Epic Games.
With that said, Season X is facing a bit of delay. As per the discovered information, the tag seasonEnd and seasonDisplayedEnd hold a bit of info.
- seasonEnd: 2019-10-17T14:00:00Z
- seasonDisplayedEnd: 2019-10-13T14:00:00Z
Over the past period, seasonDisplayEnd has been holding the right information on the ending dates, and in this case it is 4 days earlier than the seasonEnd tag.
With that said, Season 10 is most likely to finish either on 13, either in between the period in the tags, or, on 17. But, this information should be taken with a little bit of salt, because Epic Games may develop a surprise.
