It appears that Adobe, the makers of Photoshop and Illustrator (among other things), seem to be interested in Linux. Also, it looks like they are seriously considering releasing things as Open Source, too.
Just an educated guess: Adobe will probably open source some groundwork for making their apps work nicer on Linux. The list will most likely involve changes in things like the Linux kernel, GTK+, GNOME, font rendering, and in the X server.
After (and/or while) their changes have propogated, they may work on porting and releasing key apps according to some strategy. I’m not sure if that will include the heavy hitters of Adobe Creative Suite, but it would be nice. I’m guessing their first app will probably be a revised Adobe Reader (for the desktop and for Linux-based hand-helds) and then they will follow with their server stuff. Maybe after that time (or during it?) we may see other user-facing apps, like the suite.
Of course, this is all just a total guess and I really don’t know anything more than what CNet says.
