Based on that JLA image, I'd guess "modern and diverse" will mean hypIng b-list minority characters like Cyborg.
In terms of attracting new readers with a reboot, Ive got no problem with that. However, my suspicion is that DC won't fix the real problems: an over reliance on crossovers and events and overbearing attempts to homogenize the line for the sake of "branding", thereby stifling the creativity of most of the writers.
