Pretty much the only thing we don’t know is pricing. No way Apple wanted all this leaked before the event. Very sloppy from Apple employees. Someone should be fired over it.
You know nearly nothing. You know color, name, and capacity. That's nothing compared to: processor specs, graphics performance, LTE/5G, new features, new hardware, camera spec, size, battery life, Bluetooth, and dozens more pieces of information.
They did this very purposely. No one will be fired for this, as they were asked to do it (even if they weren't, people don't get fired for this kind of stuff, you don't know business).
