Checking the Wikipedia I find less than I would think about Hewlett Packard and Canon.
But they are still interested in hard copy. Both are at drupa.
So far I still think the main news is that Adobe and Apple have stopped having stands (booths).
Just checked on Google blogsearch
so there is some Adobe presence in a manner that won't muddle much with a focus on the cloud.
Can't find anything sensible on "Apple, drupa"
There is a Reuters report about TV
Apple declined to comment on what it called "speculation."
