Talk your cast speculations for the dub here.
On a sidenote, any particular reason these series haven't been added to the Funimation show forums yet, despite being licensed?

Toaru Majutsu no Index/Toaru Kagaku no Railgun dub speculation.
They probably have some issues with Geneon. Since Railgun and Index is their highest selling shows in Japan (particularly the former), they and J.C. Staff probably want high expectations for the North American release. I think there will be an ANNCast with Funimation next week.
Anyways. I was constantly revising my dub cast for this show. I would love to have Aaron Dismuke as Touma Kamijou and Alexis Tipton as Index. I would want Funimation to bring in two LA voice actors: Johnny Yong Bosch as Accelerator, and Cristina Vee as Misaka Mikoto.
EDIT: Also have a generalized "create you own dub cast thread" here
An ANNcast? Curious.
If you don't mind me asking, where did you hear this and what day is it supposed to be?
As for Geneon, I see. What does that have to do with the series getting a forum, though?
Lastly, that sounds like a pretty good cast. I can definitely imagine JYB as Accelerator.
