I'm not clear about what role the Savage Worlds Deluxe edition serves now. Are future Savage Worlds products from Pinnacle going to be released using the Deluxe rules from now on? Or will they continue to be using the Explorer's Edition rules and the Deluxe rules are a standalone book of options (similar to D&D's Unearthed Arcana)?
The answer is basically Yes. The Deluxe is meant to be round up of all the corrections from the Explorer's Edition plus expositions of the rules and some new stuff. There will be a new smaller paper back of the Deluxe edition, without the expositions
Correction - Savage Worlds Deluxe: Explorer’s Edition now available.
