They cannot, however, give an exclusive license to the old, GPL version. They cannot unlicense that work.
With large-scale projects (many contributors), you need the permission of each to change the license. This can be done, but it's not as easy as Trolltech or MySQL (say) changing their licensing conditions on their wholly-owned codebase.

The database company MySQL were taken to task for (perceived?) license drift on Slashdot recently. I think the best commentary on GPL/commercial dual licensing from that discussion was:
The poster argues basically that if you offer GPL/commercial dual licensing you have to misrepresent the GPL as noncommercial.

Yes, and all that derived work then becomes so much free advertising. The original author would need the permission of contributors to relicense their contributions, though (which they are free not to give)[is this right?].
