So if you as developer want to get the developer preview, the cost for that just went from 270€ (Nexus 5X) to over 759€ (Pixel 1), and the Pixel 1 isn't even available in major markets such as France.
So now a huge number of developers has no ability to test their apps on the latest version of Android.
For me, personally, this means I won't be able to support Android P, I won't be able to replicate bugs, and in worse case (as happened before once) I'll have significant bugs in my app, no way to replicate them, and no way to fix them, because the bug doesn't show in the emulator, and I have no device to test on.
Google's really shooting themselves in the foot by offering no way for developers to get an affordable testing device anymore.
