What is this WWDC 2017 picture telling us?

This is a part of a picture that you can download here. Take a look at the person in the upper left corner. What do you think? Is that a MacBook Pro in front of him? If you work for Apple, that would have to be a yes I guess. Even if the dimension of that keyboard and trackpad doesn’t fit a 15-inch MacBook Pro.
Ok. Now look at the one below it. Two people looking at a ‘notebook’ without a keyboard and trackpad on it. Why? That’s just weird. Not only that. It appears to be wider and has a bigger display.
There are ten other figures with the same kind of ‘notebook’. What, if anything, is Apple trying to tell us here? That one out of eleven notebooks is a MacBook Pro? Or that other brands do sell a 17-inch notebook? Nah. That can’t be it is it?
Wait. What did Tim Cook say about the pro? Ergo. Is that a new Apple device, or a 17-inch MacBook Pro with a Kaby Lake processor?
I know. It’s just a picture, but Apple is usually giving away clues/hints as to what the event is about – in terms of hardware announcements. Maybe it’s just a silly coincidence, but what do you think?
What other hardware would I love to see announced at WWDC?
Well. Ok. A new AppleTV with a faster processor and a USB-C port that actually works. Not just for diagnostic purposes. To restore the device (in the event that over-the-air restore doesn’t work). But one that could be used for external storage.
Next to that. A new Mac Pro and Mac mini. I’m also getting the next iPad Pro. Definitely.
