Players of Genshin Impact have received a Thank You mail enclosing 400 Primogems and a Wind Glider, the Wings of Shimmering Galaxy. The Thank You mail as sent by the Genshin Impact Operations Team mentions the concert, and is written as follows:
Thank You to All Our Travelers ( 1/4 )
Dear Travelers,
We sincerely thank you for your continuous support and love for Genshin Impact, and we would like to offer this thank-you gift to express our gratitude.
In addition, we have specially prepared the Genshin Impact online concert on 3 October, and we look forward to you joining us.
May Teyvat bring you more joy and cherished memories.
The paid bundles meant for the real life concert – which has since been indefinitely postponed – appear to have been repurposed for this occasion. You can find the update notes mentioning this “Boundless Symphony” bundle here. If it is indeed a repurposed gift, then the names of the items look to have been changed, with the remaining gifts presumably being the furniture, namecard and 600 Primogems to go. Notice that the mail is marked 1/4.
New Bundle “Boundless Symphony” will be added to the Shop at a later date: Purchase this bundle to receive Special Namecard Style: “Celebration: Tuneful Delight,” Special Furnishing: “Splendid Phrase,” Special Wind Glider: “Wings of Poetic Melodies,” and Primogems × 1,000.
Should the real life concert come to pass, will they be releasing an additional paid commemorative bundle? Well, let’s wait and see. In the mean time, keep an eye out for the version 2.2 livestream.
