I heard that at least in the preview video, Jack was revoiced by Mello from Death Note's English actor, if this is true, then I fear for other roles as well, I can't imagine Chase Young with a different voice, that voice needs to be done by Jason Marsden.
I don't fear for Omi's role however as Tara Strong apparently did do voice over for it. We will have to see if the series is any good and what changes if any it undertakes.
