I, personally, do not share your enthusiasm. Even if the production level of the rule books looks hight/top.

I will apply the "Wait-&-See" politics. "Wait" to get more insight on the DW rules and "See" if it is worth maintaining expansion/legalization of my DW army or just keep on using what I have already: indeed it is likely that my 100% firstborn DW based mostly on Veterans will be enough for fielding a set of supporting units as covered in the news as a small add-on force.

The opportunity to get GK Termies is however tempting... A la GK teleporting to assist SW like in 1st War for Armaggeddon... Can´t deny it

This is going to be me when BA release. Hopefully it lines up with pay day!
