Quest 4 (possible improvements) ?

Good day, My apologies if this is not posted in the correct section!

I might be a little ahead of myself, but I was wondering if the following issues from the Quest 3 are being taken into account with the upcoming Quest 4 model?

At the moment, tracking is an issue with the Quest 3 when playing many different games involving fast moments or out of the headsets sensor range, which unfortunately, can impact the user negatively.  Often, every point, swing, hit or movement matters and not having these register can leave a feeling of frustration towards the user. Is the quest 4 moving towards and emphasizing more towards hand tracking, or will sport/fast movement games also be considered?

Headset weight - Standing still or moving for a period of time can cause neck pain, pressure and possibly leading to injuries. This might be a little difficult to reduce because of all the components, but is this something that is being entertained? I think that the more balanced weight is really helping out, but I can see how reducing the combined weight can be a much more enjoyable experience for the user.

Heating from the headset - Are there any considerations to have a built-in fan or some type of cooling system built into the headset? At the moment, the headset can overheat (depending on what the users play). Currently, there are different types of options to help mitigate the heat, but could this be an added component to the future headset?  

Thank you so much!
