Yes, all six of the updated apps I was notified of this morning are missing their icons, which remain grey.
And each time I launch the App Store on my iPhone 6s (running iOS 9.0.2), initially all the other previously updated apps have a grey box where their icon should be. As has been noted, seemingly swiping up and down through this list restores the correct icons - and it seems as if you have to totally remove them from sight before swiping back up again for them to re-appear. And you need to do this in small batches.
That said, none of the six updated apps from today and four of the many that were updated over the last few days have had their icon restored. So I don't know why these ten aren't appearing at all.
Also - but this has only happened once today - when I searched for a new app, all the icons from the search results were missing, along with all their example screen shots. All replaced with grey icons or placeholder boxes.
