The keyboard looks to attach the the left side in these pics: https://www.apple.com/smart-keyboard/

While "the new Apple Pencil starts charging when you place the flat part on the right side of your iPad Pro." from: https://www.apple.com/apple-pencil/

So it looks like the answer is yes.

There was a passing screenshot in the video with both used at the same time. This was my biggest question towards the end, and I wish I'd screenshotted when I saw it. But they do look to both work together, and glad the documentation lines up with that.

I seem to recall seeing a 2 second thing where they had a pencil and keyboard attached at the same time. And I'm pretty sure they mentioned 192 magnets built into the edges of the Pro.

I'm hoping this leads to a future where 3rd party accessories snap on and charge.

I guess it doubles up as a harddisk eraser then...

They mentioned that they have magnets all over the thing.
