What is Sony Mobile announcing at the end of October?

Sorry if this has been mentioned already, but I just noticed that Sony Mobile teased an announcement for next week on Google+ (it was posted on October 20). Any thoughts/speculation/wild guesses what this might be? I assume it is android related (and not WP8 related), hence why I am posing the question here. My hunch is something mildly disappointing (e.g. JB update for some existing phones) and not new hardware, but could we see a (real) Xperia Nexus? A follow-up to the Tablet P? Something else?
