Even if costly camera components are Apple's main motivation to release an iPhone Pro, the company can't stop there if they want to release an entirely new and superior iPhone model. Perhaps putting iPad-level silicone, or at least a higher-clocked processor, in the iPhone Pro model is a given. Heck, like the MacBook and Pro before it make the iPhone Pro slightly thicker to support the more powerful processor and a larger battery - and so there are less lens size constraints. Beginning the transition to OLED by putting it in the iPhone Pro model would be very welcome by me as well.
If Apple does it right then the iPhone Pro could become an extremely popular extension of the iPhone line. My wallet is a bit concerned that it will command more than a $100 premium over the standard models but I personally hope the iPhone model lineup looks like this:
Choice of iPhone 7 or iPhone 7 Pro
Choice of 4.7" or 5.5" display on both
Choice of 32GB or 64GB on iPhone 7
Choice of 128GB and 256GB models on iPhone 7 Pro
