New Genshin Impact leaks suggest that a future patch from one of the Version 4 updates could have three banner phases. It is yet to be verified which of those patches will feature this change.
As of right now, this game operates on a two-phase banner system. If the leaks are accurate, that means players should expect to get six Character Event Wishes per update once this change is introduced. There is no guarantee that the leaks suggesting it are accurate. Similarly, there isn't much information on how long each of the three phases will last.
One leak suggests that this new format could take place before Genshin Impact 4.3, but this is subject to change. HoYoverse is yet to make any official announcements regarding this alteration.
The first leak about this matter that garnered a ton of attention is shown above. It merely states that three banner phases will be incorporated into Genshin Impact after one of the 4.X patches ("X" since it's uncertain which update it'll be).
Nothing else was revealed in this specific leak. Event Wishes in the game's current version tend to last 21 days, and that's with a system that involves two phases. If another one was added to an update, it would be logical to assume that each would last 14 days.
Still, there is no concrete evidence regarding the timeframe for the upcoming Event Wish change.
There were old rumors suggesting Genshin Impact 3.5 or 3.6 would introduce this alteration, but Travelers should know by now that can't happen in Version 3.5 at the very least. Newer leaks have changed the Version Update number from a late 3.5/3.6 to 4.0+.
Interestingly, there are more leaks related to Event Wishes than just the increase in how many of them a player gets per patch.
