Why is it iPhone X and not iPhone 9?

[iMore Question]

Why did Apple skip a number. Makes no sense to me. Is the next iPhone going to be the iPhone 12?

X is 10. It's Apple's 10th anniversary of the iPhone. No one knows what there will be next year.

I didn't notice in the Keynote that Apple mentioned why they skipped a number, so only Apple knows for sure.
