I know what Alex said, but last year they stated there would be an SDCC Ex Joe for 2014. Theoretically, it would be announced before SDCC so Alex wouldn't be lying by stating that there won't be anything new "at SDCC." They're notorious for wordplay like that. That said, honestly, if there isn't, it won't be a surprise given it's a-typical Sideshow continually fumbling the ball on yet another license and driving it to it's demise while blaming their customers for "a lack of interest." Their history is littered with incidents just like this.
Hope you are right, but I'm not that optimistic. Think the Joe line is already in the SSC cemetery
