The plan is for the Android version to be much like the iOS version. The Windows version is built using the Qt frameworks, which can run on Android, and in fact I have seen a demo of the Windows version running on an Android tablet, but as you can imagine, it is nearly unusable with the Windows, click-based UI on a tablet! The Windows developer will be creating a new UI layer based on the iOS version (but redesigned for Android) for Android devices. At the moment, though, the Windows duo are putting all efforts into the next major version of Scrivener for Windows.
All the best,
