My personal guess: no.
I think the Librem 14, for the foreseeable future, will be the only laptop line of Purism.
It’s the compromise between 13 and 15, with the case size of 13 and the screen “almost” 15.
The hope is that most customers can live with that.
For Purism that means more production volume, less overhead, possible better margins/profits and the chance on lower end customer prices.
For a similar reason, I assume they currently don’t offer international keyboard layouts.
Which I’d hope come back at some point, as I don’t see me typing on a US layout …
