The Walking Dead Companion Series in 2015

As if AMC weren't already making enough bank with their original series, they are currently working to develop a companion series to their most popular show, The Walking Dead.  Robert Kirkman, Gale Anne Hurd and David Alpert are already on board to produce.  No news yet on storyline, cast, etc.

What say you?  Leave your thoughts on whether or not you think AMC is making the right call here or not, and where you'd like to see this new series go storyline- and cast-wise.
