For the record if you are not a VEP customer yet, I think this is a pretty great deal to take advantage of, If I weren't already using it, I would be all over it. The entry point is much less now then it was in the past, with the ability to just get a single license. And FX will be included, something I think they should have done a long time ago. And if you want it, EpicOrch2 is interesting...and its on sale at the pre-order price. So frankly, if it were me and I didn't already have it, I would buy it right now at that pre-order price even if it didn't do anything new beyond what VEP6 does. Its a good price, great product. Lower entry price then ever before.
The upgrade price, however, is a different story, its higher priced then ever...and in that case most of us have no need or put much value on neither EpicOrch nor the Vienna Suite plugins..we have those bases covered already a long time ago...so...for upgraders...we need to see what is new to justify this rather expensive upgrade price, especially if we had any plans to use at least one remote VEP server...
I think if you are worried about the pre-order information in order to buy it as a new user, you're worrying too much, just get it. Upgraders aren't being offered a pre-order price, so makes sense to wait and see.
