At this time, it looks like there is no definitive information regarding a new drone from DJI. However, there have been some rumors that new models may be in the works. In August 2020, there were reports of a new Mavic Air 2 being announced and that it could be released by September. However, this has not yet been confirmed by DJI. Until an official announcement is made, it's impossible to say if a new drone from DJI is imminent or even in the works.
We would suggest staying up to date with news from DJI and keeping an eye on their social media and official website for updates. If a new drone is announced in the future, chances are it will be featured prominently on DJI's online platforms.
