The developers from the Mihoyo studio not so long ago were forced to switch to remote work, creating fresh content for Genshin Impact . For this reason, the team does not have time to finish all the work on time, and therefore the release of updates 2.7 and 2.8 will take place a month later from the original plans.
At the moment, the team experiences the most problems when writing voice acting for characters, which is very difficult to do at home. The update itself 2.7 is almost ready, but the plug occurred at the stage of preparing the presentation.
Thus, the release of Genshin Impact 2.7 can take place either in mid -May, or in early June. As for Patch 2.8, his output, apparently, would be delayed – initially the update was planned to be released on June 15, but now we will see fresh content from it only in July.
