Today Asus announced a launch event which will go live on May 12 where they will launch Zenfone 8. This event will start on May 12 at 01:00 PM (UTC-5)/ 07:00 PM (UTC+2)/MAY 13 01:00 AM (UTC+8). Asus unveiled this through a landing page on their website.

Although this hints arrival of only one smartphone but if rumours were to go by Asus might be launch three smartphones at this event — all under Zenfone 8 series.
Asus is touting something “big on performance” which we already will be Snapdragon 888 SOC. They are also promising “Compact in size” so maybe mini version will also be their.
