All 35 of them? No. If those 35 had it to do over again they'd switch to Alibre because it will do what they need for less than $2,000 US.
That is, of course, a facetious statement but unless you can provide some substantiated or at least industry accepted numbers what's the point of the question? To create an illusion?
Compete in what way? "Compete" is a word the ignorant love to use while they are incapable of comprehending the nature of the competition. Instead of asking something so vague why not initiate a discussion polling Pro/E users about their experiences regarding native vs. third party applications for a specific type of "production work"? Anything offered by non-users; e.g. "I looked at it once", "I used it years ago", etc., is worthless. When it's all done and collated you will still be just as confused by the big picture but you can at least examine the details for relevant tidbits.
That's an extremely stupid question. Anyone knows it depends on goals never to be known by end users and market variables not yet defined.
Another vague, stupid question. Wildfire and Wildfire 2.0 converted enough functions so an archaic UI won't contribute to the terminal intimidation of new users; be they from the grassy pastures of AutoCAD users grappling with parametric 3D as well, or those bumping the low end capability ceiling. WF3 is probably the culmination of a focused effort to modernize the UI. What happens next depends on the goals and variables mentioned above.
Based on the nature of your questions I forecast you will not be impressed by WF3. Microsoft considers the learning impaired sector of the market worth developing for. High end design and manufacturing software vendors can not and will not.
BTW, What IS a Banquerite? It appears to me you're comprehension of the subject matter would be rivaled by an intelligent fifth grade student.
