One could only speculate, but my guess is that there will be MAJOR changes. I'll bet that old licenses will have to be upgraded and that the software will be tied down to an online account managed by l*gos. Hence "...is the iPhone of Bible software".
Just my speculation, but why would they leave even
one loophole for the unl*cker/lic*nce or other (known) method to work. This is the reality of software cr@cking, especially when concerning an expensive app. when we know the company's owners are fully aware of the methods being used.
Of course if v3 can be reversed, then so can v4 most likely....eventually
