Did you purchase MapPoint 2002? That's the latest version. The new one will probably be called MapPoint 2004 and will come out this summer.
I think the reason they skipped a year was to focus on the launch of MapPoint .NET (now called MapPoint Web Services). I don't know if they will wait two years again for the next version, but I doubt it..
Note there was a recent article on how you may have some success merging the AutoRoute 2003 data ($30-ish I think) into MapPoint 2002 Europe:

Good luck!
