I agree with Deckiller. While I'm more biased with the VX, as it's my editor of choice and the VX is more than capable of doing the same things as its predecessors, one would have to completely start from scratch, learn the limitations of the VX, as well as learn how to either script or implement scripts before switching over to the VX, which would in turn delay these games even further.
On a second note, I've had both of these episodes on my computer forever, and actually started playing the first one a couple of months back before I found out it was being completely altered. It may be in my best interest to wait and see what comes out of this.
