Jeff,
Essentially yes. I’m not sure on the specific version of WTP as our initial integration was based on the initial contribution, but since then we have ported and created 100s of bug fixes and integration changes to the code base, so I don’t have a specific answer for you.
For EMF and GEF, with 4.0 we will ship the most recent stable releases of both of those packages, which is also what VE currently relies on.
