I wonder if the OS will get a complete makeover ? Seems like Google does a total revamp of the OS one year, with two two releases after that, and then moves to a whole new redesign again;
- Ice Cream Sandwich was a big revamp, followed by bug patches and tweaks added in Jellybean and then KitKat
- Lollipop was a whole new redesign, followed by tweaks with Marshmallow and now Nougat
- Will O be the next major redesign ?
The funny thing is JB and KK were 4.x releases. So you wouldn't expect major enhancements visually. But since then they have gone full version numbers. Lollipop got a makeover with 5. MM didn't really with 6. Now Nougat is 7 and isn't really much visually, but a lot behind the scenes. So hard to say what they are going to do there.
