I don't see it's coming again. ROG 3 is already in the market and it's much more higher priced then ROG 2. Asus want to market the ROG 3 as it will give them higher profit then the ROG 2. Especially in India where 5g will not gonna come before 2022, investing those extra thousands doesn't make sense and lot of people knows that. So, people will go for ROG 2 instead of ROG 3 if it's available and Asus don't want that. So, don't wait for ROG 2. It will not be available again.
