Then check out this article, written by Heather Kelly and presented on CNN.com:

What to expect with the iPhone 8

The subheadline states:

Tim Cook probably wishes people were a little less excited about the next iPhone.

In other words, don’t expect a revolutionary new phone.  It would appear those days are over -for now anyway- and every new iteration of the iPhone looks to have incremental changes, including lighter weight, better processors, better cameras, etc.

Just don’t expect anything revolutionary.
