boldsuck I'm hoping that Pixel 9 Pro and Pixel 9 Pro XL will also have 16GB of RAM, honestly. Remember that these phones will be supported for 7 years. It's good for them to have specs which seem unneeded now. During that 7 year period, they might very well be able to take advantage of that.
As an example, when GrapheneOS makes an app to be able to run and manage virtual machines, the extra RAM will certainly come in handy. :)
