Considering
WOTC's slow to respond ways in other areas (often taking up to 6 months to formulate a reply), I think everyone should view it as a good sign that
WOTC is being so proactive so quickly.
Here are the major changes we should be expecting to see (disregarding minor irritants to selective individuals, irritating to some, laudable to others):
1) Periodical publishers inability to support past issues. (Subsection 6.1)
2) Once changed to
GSL, product line cannot be changed back to
OGL, meaning the product rises or falls with
4e. (Subsection 6.1)
3) Licensee's inability to use their own IP after the termination of the
GSL (Subsection 6.1, 6.1b)
4) No cushion period or protections for licensee for termination of
GSL (Subsection 11.1)
5) Total destruction of product line upon termination of
GSL (Subsection 11.3)
