I am trying to think forward to Learning Technologies 2011. A bit of time travel is sometimes useful. From the recent earnings meeting it seems Adobe will concentrate on Flash for CS5 but Acrobat will be updated later in the year, maybe mostly in the cloud. My guess is that Learning Technologies will still be mostly Flash but PDF and flat pages will be in there somewhere. Many people will consider Google docs and other lower cost options, also online document networks such as Scribd and Slideshare. Both have a design that seems to be interested in documents even though Flash is in there to display the pages. Adobe design is always pushing us somewhere else I find. So this sort of situation exists now even though some products are not launched or widely available.
I have put more about this in the Sandbox board for Networked Learning.
