Apple should, at the very least, introduce the iPhone 7 and an iPhone 7 Plus model in September. Right now, it's still unclear if there's an iPhone 7 "Pro" model as well, or if that's going to launch at a later date (or never.) A new note from Deutsche Bank analysts, obtained by Business Insider, adds a few more predictions for what we might expect from the iPhone 7 Plus.

The analyst report said Apple will launch an iPhone 7 plus with "a dual camera for better zoom and 3GB of RAM." It also predicts the device will have "better sound  – possibly stereo sound" and "professional class water-proofing." That lines up with plenty of other rumors, so Deutsche Bank may simply be following the same news we all are, though it credits its knowledge with"supply-chain checks."

The bank also added Apple may still release a special new color, either black or dark blue, to help distinguish the new phone from earlier launches. That rumor seems to have been debunked, but maybe Deutsche Bank knows something we don't.

Interestingly, the analyst report also suggests Apple will indeed include a Lightning to audio dongle for the iPhone 7 and iPhone 7 Plus, instead of including Lightning headphones in the box. We'll find out in September.
