The antenna issue was largely created by blogs and media outlets. Apple sold the bumpers before that whole frenzy began, and since they provide some lay on table protection without completely hiding the beauty of the phone, I'm sure apple will sell bumpers for the verizon phone.
What I'm sure will be frustrating for many verizon iPhone users is the initial incompatibility with every good case\full skinset out on the market now
UCLAKoolMan is right, Antennagate was nothing more than a media outrage, wasn't much of an issue to begin with. As for the bumper, Apple will be making a new version for the VZ iPhone. However, I'd recommend getting the Pop! by case-mate. They're available on their website under the Verizon iPhone 4 Lineup.
