So far KDE is a community-only solution. So far no OEMs has shown any interest in pre-install KDE even if it would become a working solution. Unfortunately I don’t have the ability to see into the future, but I can use the past and the present to get ideas for the future. The past tells me that there are other community-only solutions which are not available as OEM pre-installs. I do not know of any OEM which pre-install GNOME and from all I have heard it’s even impossible to pre-install GNOME on non-community OS. Given that it is quite likely that KDE will go the same road. It’s designed as a solution for community and if OEMs don’t pre-install GNOME there is no need to pre-install KDE.
No fact here, just try to mimic Martin's writing style.
