At least we don't have any picture of a switch yet. Judging from the rest of the pictures, showing that monorails are just re-textured metros, it could be possible. However, I don't know how CO could have designed a switch in a way that it looks remotely realistic. So it could also be that switches are not possible at all. I think we just have to wait and seeIs it possible to build embranchments in monorails? I don't know if I use the correct word but is it possible for one line to go into two directions from one point, just like the letter Y?
I'm not sure who, and why.
But some of us had the monorail dlc in our dlc list for a while now.
And have actually thus unlocked the unreleased monorails right now.
My guess its the beta testers, or pre orderers or something...
Not sure if it was an intentional gift, but i'm definitely not complaining.
