... but isn't it using a wireless dongle to connect to the headset to the PC so HDMI doesn't get involved?
It seems to me the wireless is pretty important. I have an MQ3 and I have the link cable. For software development I pretty much have to plug the MQ3 into my PC and it is not so bad to wander around the living room looking in a Mars boulder from all sides and such.
For games and apps that involve moving around, particularly things like Beat Saber or Supernatural the standalone headset has a huge advantage of having no cable. If I have a choice between buying a game on Steam or the MQ3 store I'm likely to buy the MQ3 game because of the convenience and freedom of standalone. A really good wireless link changes that.
