For many veteran DC fans like myself, we're hoping #Rebirth will result in a clean reboot of the current continuity and a reinstating of the more iconic status quos for various DC characters, even if we don't get any of the previous continuities back. Considering the tough year 2015 was for both DC Comics and DC fans alike, bringing the characters back to a more recognisable place seems like the more logical approach. After all, despite Convergence not selling at the sales numbers DC wanted, it was still the highest number of sales they saw in ALL of 2015!
Obviously, I don't know what to expect with the initiative, but I do know what I want to see happen in the months to come for me to fully invest in DC Comics again. Most of this I've talked about already.
