At SWW 2011 it was told that solidworks would give at least a 2 year
window before extinguishing workgroup. And it was said that Solidworks
had not annouced such a thing up to that point.
Workgroup PDM is not going away. If it is ever cancelled (which is highly unlikely), the user base will have a 2 year notice prior to its end-of-life, according to SolidWorks Corp.
I've caught two major west coast VARs blanantly lying to their customers by telling them repeatedly year-after-year that it's going to be killed off by the end of the year. If all those "rumors" were true, Workgroup PDM has been cancelled at least 7 years in a row. Workgroup PDM is beneficial to the SolidWorks menu because it's a gateway to Enterprise PDM. Once users are hooked on Workgroup, it's not that difficult to get them to buy into Enterprise when their operation expands beyond Workgroup capabilities. It is possible to move your Workgroup vault (intact) into Enterprise.
