According to reports, Google plans to continue only offering 128 GB and 256 GB of storage with its flagship smartphones in Europe. While the US may receive a 512 GB variant of the Pixel 7 Pro, non-expandable storage means that there will be no way to push the Pixel 7 series beyond 256 GB in Europe. Google has confirmed that there will be colour exclusives for the Pixel 7 and Pixel 7 Pro too.https://www.notebookcheck.net/Google-Pixel-7-series-to-launch-without-512-GB-storage-option-in-Europe.650483.0.html
