Chillax folks... you never know Apple might use the new hinge but with the same shape or similar depth/shape/structure keys. The iPPro keyboard is closer to the pro keyboard but uses the new hinge and is nothing like the new Macbook in form. Go look here
www.apple.com.
An OLED touch bar that is basically a second or extension to main screen as a touchscreen that works natively may be amazing, a pro feature, where pro apps can place there custom hotkeys or the dock as other have suggested and it will probably customisable oh like the dock already is so the dock with native support for app developers to improve user touch interactions on a surface that's not on the screen. Makes a lot of sense. I think we've all had similar ideas for years.
Also consider this, if you have ever used a wacom it's novel to see without the obtrusion of your hand covering what you are working on, the full screen working right before you eyes. Reaching up to touch a screen in a sitting position is not good ergonomics. Standing at a POS yes but not sitting at a desktop.
The OLED bar coudl house all the play controls and such so it never has to appear on screen, pretty cool when in full screen mode don't ya think? No need to fiddle to get rid of the mouse pointer.
Personally I like the new hinge and both keyboards too. I'm very eager to hear of this MBP update. Sounds like a buy in.
Yes some of these features have been on ten year old PC laptops but the experience has been mediocre. If Apple integrate and support it from OS to hardware it has a better chance of being very cool and totally normal.
The might roll out update USB keyboards.
