Elgyfu I upgraded to Poser 4 from the free version of Poser 3 when it was given away a few years ago by 3D World in the UK, it was actually a special upgrade offer in the magazine at the time and have recently upgraded from Poser4/Pro Pack to Poser 5. When you install the upgrade version of Poser 5 it is a completely separate installation and you have to enter 2 serial no's, the Poser 5 serial no and the serial no of the version of Poser you are upgrading from. So I think there is a good chance that you could get Poser 5 as an upgrade from the version you have, but as Jaqui says the final decision will be made by Curious Labs so why not give them a call, and look forward to a huge change from your Poser 3.
