Yeah, let me know when less than 25 developers crank out a working mobile Linux distro that will continue to be supported in 5 years. Looking at all the failed projects in the past and all the managements complexities like software support, modern touch integration this is virtually impossible. They'll likely have a brief stint releasing some Debian ARM based mobile OS with a limited selection of software. You'll get some GTK Calendar, Calculator, etc. The basic crap that imitates Android phones from 2011. And it will be supported by up to 5 or so devices, hopefully without some impractical rooting method.
Linux barely exists as a desktop operating system as is. The only difference nowadays is smartphones don't have that freedom of customization desktops provide. Smartphones are consumer centric devices, you can't even swap batteries anymore. Leading OEMs have no interest in supporting an obscure operating system, they know the majority of users want Android.
When Purism releases this as an OOTB product, it will without a doubt run on some no named Chinese Phone that holds the mediocre power of any low end Android Device. Only it will be $600, rather than $180
