Will Pages/Keynote/Numbers be free for old macs?
It appears that everyone that owns an older copy of iWork for iOS gets a free upgrade whether or not your version came from a retail CD or the Mac App Store.

If you don't already own iWork - you will have to pay for either a new Mac or the apps piecemeal on the App Store.

The above summary is my understanding of this MacWorld article that includes calls with Apple Press relations and an "on-the-record" confirmation that all owners of iWork should get free upgrades despite some glitches in the initial roll out today.
