If these 4 parameters (higher resolution, higher bitrate, larger sensor, update to 10bit video) are improved on the Insta360 X6, I'll be very happy, because we'll have a 360-camera beast. We'll see what really comes of it.

Desirable Insta360 X6 improvements

Besides the already above defined specifications of the Insta360 X6, which are very likely from my point of view, there are some other improvements which would be really desirable:

• Stiching
  While the Insta360 X4 already boasts impressive stitching, further refinements would be a welcome improvement on the X5

• Frame rate/ slow motion
  It would also be great if Insta360 would increase the frame rate and resolution of 360 videos. With the X3 and the ONE X2, a maximum of 360-video with 3K and 100fps is possible. The Insta360 X4 has made significant strides in slow-motion capabilities, enabling users to capture 4K footage at 100fps and achieve Bullet Time effects at a maximum of 240fps.
  
  An increase to 8K @ 60fps or 5.7K @ 120fps would be terrific. This would allow users to create stunning 360-SloMo videos.
  
  Here is a 360 SloMo sample video created with the Insta360 X4:

• Exchangable lenses
  360- camera are designed to record 2x 180° fisheye videos. The disadvantage are the protruding lenses, which can easily scratch. It would be desirable if the lenses of the Insta360 X5 were replaceable. A damaged, scratched lens makes a 360 camera unusable. Replaceable lenses would be a step towards ease of maintenance and user-friendliness. Let's hope that Insta360 brings improvements here with the Insta360 X5!

• 10bit 360-video
  The addition of 10-bit recording would offer a substantial advantage in post-production, granting users greater latitude for color grading and dynamic range adjustments. Nevertheless, as the Insta360 X series is targeted at consumers, the inclusion of 10-bit 360 video in the X5 remains uncertain. This feature is typically associated with professional workflows. Still, it's worth hoping for.

• Dual SD card
  As video resolution and bitrate increase, the data rate also increases massively. Micro SD cards are improving all the time, but the high amount of data generated by 360 videos could bring the micro SD cards currently available on the market to their limit. A micro dual SD card slot would be a remedy.
  
  Here, the individual videos can be stored on different SD cards. In terms of user-friendliness, however, there are a few arguments against this. The user would always have to read two memory cards in a dual SD slot. Therefore, I estimated the probabilities to be very low here as well.
