Whenever dji will kindly provide a firmware update for Mini 2 SE that will add 4k and 100 Mbps capabilities (thus basically upgrading it to Mini 4k) I will gladly pay for it!
Fingers crossed!

Hi, djiuser_dacair. Thank you for reaching out. We can't guarantee this update but I will take it as a suggestion of yours and will forward it to our designated team for attention. All significant suggestions will be implemented after the evaluation of our relevant team. For the latest updates please stay tuned to our DJI official website at ( www.dji.com ). Thank you.

They would have done that already if it was possible instead of releasing a "new model", which as we can see according to FCC filing is just a Mini 2 SE with new camera module (and new wireless chips, but those have same functionality and are just updated part numbers). See https://fccid.io/SS3-MT2SD22/Letter/C2PC-Letter-7211456.pdf - specifically this part:

"1. Add an alternative camera chip H22A55. (Comparing to the original camera chip H22A35, the alternative H22A55 chip has 4k function, which not supported by H22A35)"

Browsing the net does not reveal any info about differences between the two chips.

However, it seems that the whole H22 class has native 4K capabilities:

Therefore, I'm still keeping my fingers crossed...

Crossed my finger too with you bro. And have my other finger crossed for litchi support on mini 2se.

Chipset also supports HDR processing.  Suspect the 4K and 2 SE have been down spec’d as to not take sales away from the Mini Pros or the sensor isn’t up to the job.
