Will iPhone 6 be supported with iOS 13?

I've currently have my iphone 6 for about 4 years now and I still have the latest version of ios on it and I wonder if it will be pushed to more softwares such as ios 13 and 14? Please let me know about your predictions on how far iPhone 6 will be supported in terms of software.

No.

Yes. Assuming Apple's update cycle the 5s would be dropped this year ending with the last version of iOS 12. The iPhone 6 would get iOS 13 but then itself would be dropped with the last version of that before iOS 14 in 2020.
