I wonder if you have a view on VR? I am very excited about its potential. I expect to see many more apps and phones developed to support it.
More than 10 million phones are expected to be launched this year supporting Google Daydream, including Samsung's Galaxy 8 family and LG's flagship phones. There are already more than 150 apps supporting Daydream. And more than 10,000 360 degree videos posted on YouTube. Clearly as the original Pixel supports Daydream, the next Pixels will too. I will wish to keep up with this trend and a newer Pixel with better display (OLED wrap around?) and better Chrome OS support should help.
Add to the mix Google's recently announced Visual Positioning Service, and integrating it with GPS, should open a huge market for VR and AR applications. One immediate application was showcased at I/O where holding up your Tango-ready phone in a large store like Homebase or PCWorld Currys and instead of getting lost your phone guides you to the correct aisle and shelf where you want to find a particular item (indoor mapping made simple). Asus' Tango-ready Zen Phone AR, to be launched later this year, should attract attention too. This is just one of many possible applications.
For those who are visually impaired, audio interfaces paired with VPS could help them find their way around a lot better.
Smartphones "hitting a brick wall"? I think not.
I agree VR is a big thing and has huge potential, however it's not something I am excited about and therefore not something I look for in a phone. I just feel my 6p does everything I could want it to do, and spending £100's on an upgrade is only going to give me things I'm not really going to use.
The brick wall is just a personal thing really, the main aspects of the phone have reached somewhat of a peak and haven't improved such as the screen, camera, performance and battery life. While they make incremental upgrades to them, it's not a night and day difference like it was a few hears back going from a VGA res screen to HD, cameras going from 1.2mp to 5mp etc.
I just feel where I used to upgrade every year, and feel a massive improvement from it, I can now easily wait 2 years before upgrading because there's nothing that particularly excites me from it any more.
