A Google launch event was recently confirmed in New York under the headline "Come see a few new things Made by Google", however, no specific information was shared and we still haven't got final confirmation on the existence of an XL or the rumoured XL 5G version.
With that said, however, since the Google Pixel 4 seems to have become Google's worst kept secret in terms of specs, we are fairly sure that it will have multiple lenses, at least 6 GB of RAM and most likely Snapdragon 855, unless they, for some reason, decided to change in the last second.
For Stadia users, this will also be a very interesting event as Stadia will only work with Google phones at launch.
