It’s possible Purism is holding out on major updates for a special announcement. Things like final design, final specs and hardware choices. I’m guessing this because of manufacturing time. To deliver a phone in 2 to 3 months production needs to be going on now. Cooking boards, semiconductor placement and wave soldering machines are fast but manufacturing companies won’t have them sitting idle. There’s also post production (packaging and such, unless Purism does that in house?) to be done followed by shipping to Purism.
If my logic is sound and Purism is staying true to their word as far as price going up just before shipping and the recent Librem Social comment a phone should be in production now.
