Remember the LG G5 with the bulky module? It might be a camera-centric grip with a 1,100mAh battery inside

Mr Blass also reveals that LG has another module in the portfolio, an audio-centric one. Called LG Hi-Fi Plus, it will allegedly improve the native audio output of the device. It is also said that other devices will be able to connect to the Hi-Fi Plus module in order to enhance their audio, which sounds a bit sketchy at this point. We guess further details will be more than welcome.
Blass says all of these will be part of an accessory ecosystem, reportedly called "G5 and Friends". Part of it might also be LG's rumored 360-degree VR headset and a... drone, dubbed "Rolling Bot"? Yes, it looks as if LG might have unleashed its imagination on the accessory front this time around. Solely judging by the name, we might speculate that it will probably look like Star Wars: Episode VII - The Force Awakens' BB-8 droid, though that's a nerdy fantasy of ours. Supposedly, the LG Rolling Bot will be able to roll around your house, turn smart appliances on and/or off, and even allow you to interact with your pets, if you're that lazy.
We guess LG will have lots of details to uncover come its pre-MWC keynote, provided that all of these turn out to be real, of course!
