It is generally known by now that some next version of MapPoint (2005, 2006 ?) is in the works though what form it will take is still very much under wraps. (The biggest outstanding questions is perhaps data for Brazil and Australia which are already in the MapPoint Web Service or will be shortly.)
What would you like to see in the next version? Let's compile a list for the MapPoint team at Microsoft before the specs for the new version are set in stone, maybe they will be able to consider some things or get some good ideas.
