I'll jump in on this. I bought a MacPro1,1 over 4 years ago to replace my failed G4 MDD 2x1.42. I have since filled the HD bays (System, System Clone, Media, Time Machine), upgraded the RAM twice, added an eSATA card, upgraded the video card, and added video IO (Intensity Pro).
Though my situation is a bit different than most, since I will often work on freelance motion design & video post from home. Honestly, I can't see much use for a MacPro beyond the film & video post market. Most graphic designers & photographers I know have moved on to iMacs or MacBook Pros.
What would be unfortunate for Apple if they discontinue the Mac Pros is that almost all the software I use at this point (After Effects, Photoshop, Illustrator, Cinema4D, and several plugins) is platform agnostic. Shops that need the power and are due for an upgrade will switch to Windows systems. This could then lead to a reverse Apple halo effect where people (like me) who have been invested in Macs for so long can realize that Windows & PC workstations are in fact a usable alternative and resemble little of the WindowsXP experience they probably migrated from. Then when it's time to upgrade at home, they might more seriously consider a Windows box. Then what about that iPhone? Then they start talking to their family & friends about how much better Windows has gotten (Keep in mind, that was all hypothetical.)
While iOS has been a huge boon to Apple, they seem to have forgotten that there were a good number of people who migrated to Macs based on recommendations from pros (family & friends) who were working with them, the "cool" factor of seeing high-profile films & other jobs completed with them, or a combination of the two. However, in a post PC world, perhaps the Mac overall will be less & less relevant to Apple. Time will tell and few outside of Cupertino know the answers.
