The upcoming Chicago Comics and Entertainment Expo (April 16-18, 2010) has confirmed Geoff Johns as a guest of honor. Since Ethan Van Sciver was announced back in August, that means that the Flash: Rebirth and Green Lantern: Rebirth writer/artist team will both be appearing at C2E2 next spring.
This also means that neither of them will appear at Wizard’s Anaheim Comic Con, held the same weekend.
