If they have it running on Android there is simply no excuse not to have it running on Linux.
Coding a UI and some video isn't a zero-time process, but it's practically trivial (i.e., they could have an intern or two do it).
I can understand the growth predictions from one and the other but honestly don't see what's the difficulty on writing a multi-platform player, it cannot be because of the DRM requirements I would assume, since they already have it for a linux based machine.
