So the usual look and nothing surprising.
They did their “new and surprising” earlier this year. 1-port ultra thin MacBook, iPhone 6+, Apple Watch.
Remember, Apple has a VERY small slate of products - and that’s how they keep it. Expansion of the line is sparing, Watch having done plenty of that for the year. Updates are typically incremental, and having done so to a bit of the line now is time to expand those changes across the line (retina for all iMacs; USB-C for all MacBooks; + sized iPad; >= 4K displays for AppleTV and Mac Pro).
Do you seriously expect something more “unusual and surprising”? got examples? an electric car maybe?
