It's getting very close and TGC have already published at least one app (and maybe others) to the Android market. I wouldn't think it will take too much longer. Once compiling the APK is provided, there are only two issues remaining for me that will keep me from publishing to the Android market:
1 - The orientation is still sideways for taskbars and virtual keyboards. Needs to be properly aligned on all devices.
2 - App media is left exposed and accessible on the device, so some way to just package everything together is needed (and this may be provided by the APK compiling).
