sogman First of all, I don't recommend you to invest in AVP if you plan to use it for video consumption mainly, because it uses the M2 chip which lacks support of AV1 hardware decoding (Most of future videos will use it for better quality).
Personally, the only big deal about AVP is its high resolution OLED screens, other than that I don't have any interest in it because of its closed ecosystem which limits what you can do in VR.
And for the "Spatial Video" format they are trying to push, which is the SAME Stereoscopic videos we have for more that 100 years (It's just a flat video with depth ONLY) it lacks both immersive FOV and real life scale for characters and objects we used to love in VR Videos. In other words, it's an older tech than VR and it's not better or more enjoyable.
As for the upcoming VR headsets, here you go (To make things more organized):
