I think that for the retail release, they don’t need to carry on the 5K/8K nomenclature, it could be damaging in the long run.
Maybe rename the models to something more fancy and enigmatic like Pimax Horizon, Pimax Obsidian or Pimax Obelisk, to increase brand sophistication. I don’t know, maybe I went too far with the choices, but it’s the naming concept what’s important to capture the imagination of the consumer. the Rift and Vive branding is a clear example, 5K/8K doesn’t capture anything, it’s not even descriptive accurate.
Also, maybe I would differentiate the models with different colors.
