Will there be a new Android version for FP1? And is it possible that FP could use the coming Google Andromeda? Or is some new OS in sight which could be used instead of Andromeda?
Yes, there will be a new version of Android for FP1: Android 4.4 Kitkat
No, it will never run Google Andromeda.
And yes, you are very welcome to ask questions like this during the AMA mentioned by @urs_lesse
