Nothing else will enter beta for iOS 10 after 10.3.3, even if we got a 10.3.4. The is because it is now impossible to get the PB file for iOS 10. Apple only has the iOS 11 PB profile available. iOS 10 betas are done as soon as 10.3.3 drops to the public.
No need to argue. I was just speculating a little. Also I am already on 11 since day one of the first Developer Beta and 10.whatever means nothing to me since then. But I like this thread. It's kinda funny.
