An e-mail conversation between Nvidia AIC partners (add-in cards) and a retailer leaked to the internet and obtained by Gamer Meld. The e-mail confirms the launch date for at least 4 SKUs of the 11-series GeForce graphics card. The 4 graphics cards include the GTX 1180, GeForce 1170, a product that looks like the new GTX 1180+, and the mid-range GTX 1160 graphics card. The date written on e-mail seems to be the date of availability of the card to the consumer. So that product launches and reviews as usual will overtake.

August 30, 2018 is the debut of the 11th Nvidia GeForce series card that was started by the GTX 1180 as a high-end card. The GTX 1180 card is a successor of the GTX 1080 and will be introduced as a product enthusiast. A month later, precisely September 30, 2018, Nvidia will launch 2 SKUs together, namely the GTX 1170 which is a successor to the GTX 1070 and a GTX 1180+ card which seems to be an additional brand with performance above the GTX 1180 but still below the GTX 1180 Ti (if indeed there is). While the mid-range GTX 1160 card will be available on October 30, 2018 to prepare for thanksgiving, Christmas and New Year holidays.
