Do you think that the Huawei P50 will have Google services when Joe Biden takes the helm in the US?
Or how do you see it at the moment?
Nobody can say that. Huawei will do a hell of a lot to get into such dependency on Google again. As soon as your own OS is ready, Android will probably fly completely from the devices.
This is the future, nobody can or wants to answer that seriously at the moment
If the P50 should still be delivered with Android, then you can install the Google services, as is currently the case with the P40, using a little trick
And their own OS should be available for individual devices from spring
