Still, Studio tools is a very minor actor in the CAD market. the estimation of 1 studio tools for 3 solidworks is imho very optimistic. All small to medium companies wont even consider it when choosing their CAD package.
and the fact inventor failed to attract customers is due to lack of Autodesk giving what their customers wanted in time. Now they have switched it is too late.
Solidworks, Pro/E and Catia (the latter mostly in europa) have now such a stronghold of key customers that were previously in autodesk hands, that there is very little chance Autodesk will return to the former glory of Autocad times. Other actors like Missler Topsolid are ahead too in specialized markets.
To make things worse for studio tools, Solidworks change its format at each release (1 per year) and its mother company (Dassault systemes) is also the editor of Catia which is a more direct competitor of ST in Automotive and Aerospace industries. So i wont bet the hability of ST to read native SW format is here to stay.
