GrapheneOS is collaborating with a hw vendor to create a device that can run GOS and which has similar hw to current Pixel devices. https://twitter.com/GrapheneOS/status/1490518600339308544
I have been a happy GOS user for years. Sadly, my Pixel 3a EOL is next month. I opted for an iPhone this time as they generally are supported for longer periods of time.
Maybe my next phone will be a phone designed for GOS :)
My personal hunch is that this might have something to do with the GOS collaboration announcement: https://www.androidpolice.com/osom-ov1-exclusive/
