We currently have our hands full with The Quest 2. (And me additionally with updating the editor for The Quest so it can be used by everyone.) We plan to implement better controller support for The Quest 2 (The Quest is not exactly controller friendly). Although that'll be good for the PC too, it's main aim is to ease porting to consoles, as we would like to have The Quest 2 on as many platforms as is reasonable.

After The Quest 2 is out and can be deemed a success on consoles, we'll more than likely port The Quest too.
Why not port The Quest now?
There are two interdependent reasons. The first, as I've written, is that it's controller support is quite rudimentary. It'll need substantial work to update the user interface for it, which is time we would have to take away from The Quest 2. The second one is that we just don't know how successful the Quest games can be on consoles. We cannot risk spending time (and money) now on releasing The Quest on consoles, when The Quest 2 needs so much work (and will hopefully provide a more dependable source of income).
I can guess a question.

When will we release The Quest 2? I don't know yet. If everything goes as planned, this year. If not, next year.
