For other FFG Star Wars Games, it is common to announce the next product shortly after the previous releases, even after a soft release or prerelease. I, for one, would be surprised if they didn't go ahead and announce another set that will release at or around Gencon, and Gencon will announce the details of the Base Set for holiday release.
Anyone else think we'll get a Destiny announcement? SoR was announced shortly after release. It's been 4 months and SoR is on the immediate horizon. Gencon is 4 months away. Seems logical.
