As we said we are prepping the Android Beta for its first release and due to the fact we are going to allow a LOT of Android testers to get as many device types that are eligible as we can. Well that makes it take a bit longer because we don't want a "Alpha Style" release. We want the beta to be solid and go from there.
We know people are anxious to play, but releasing a sub par product isn't something we want to do even in beta phases.
The sign ups are coming soon.
