From the announcement:
We will have a store selling all our wonderful products, pre-releases of new M2e miniatures, the new M2e Rulebook and Arsenal Boxes. Also we will have two box sets exclusive to Gen Con.
• Herald of Obliteration, Nightmare Edition
• Miss Step, Steamborg Executioner
Everything we sell at the convention is also available in our web store during the convention dates, so even if you can't make it to Indy, you can get Wyrd.
