Just like the Pixel 2 XL, the Ultra Pixel could feature a 2:1 Full vision display while the Standard Pixel 2 will feature huge chin to the top and the bottom, just like the 2016 Pixel phones.
Here's another Image revealing the Ultra Pixel with almost no side bezels just like the Samsung Galaxy S8 and Note 8. The Image also says "The future at Android is Fluid".
That said, Google might release the Ultra Pixel alongside the Pixel 2 and Pixel 2 XL. Thoughts?
Update: According to the latest information we got, the leak is likely fake.
