As a WS users I gain a "free" copy of Logos 8. I also have the opportunity to upgrade at a discount.
What I can't tell is if this upgrade, or the other "levels" of Logos, actually change the product (i.e., add new capability) or simply provide a packaged expansion of the references (i.e., books) included.
If it is just the references/books included, then waiting for the migration to near completion makes sense.
If there is actually different capability, it would be nice to understand that. The comparisons seem to focus on the library.....
