You can ALWAYS point to stuff that didn't pan out, but more often than not they got the big things right. Right down to the design. I'd say the rumors are usually at least 85% accurate lately.
Fair enough - but what out of what we currently know will turn out to be true?
Wireless charging or not? No part leaks for the iPhone 7S so is that happening or will we just see an iPhone 8? Still lots to play for, so to speak.
I remember this time in 2014 there were so few leaks to suggest a 5.5 inch iPhone that some people thought there wouldn't be a 6Plus.
