saw this article, it says its only available at the IDW booth http://www.bleedingcool.com/2016/07...isiting-the-idw-booth-at-san-diego-comic-con/
Not to worry, though - this is just a collection of the two "Road to Revolution" prologue strips that are appearing in the back of July and August's IDW titles. We've seen the first one already, and both are included in next week's Titans Return as well.
I imagine they will also be included in the graphic novel collections for Revolution.... My guess is they will split the whole Revolution event over 2 graphic novels to cover all the tie-ins.
