Any redesign and reimplementation of orbiter is going to take a looooong time. I don't think it would be a waste to have an Android Orbiter - at least a basic one - before that happens to cover us for the mean time. It would attract attention to the project, at the very least, and it would be a very useful feature. Not to mention the "wow factor" of being able to control your house with a fairly famous phone...
I'm quite interested in seeing some actual prototype implementations. I'd love to get into it myself, but I have other (not-open-source) projects that need to be finished before I can do that - they're already several months overdue, of course, so pressure is high there...
