Always.
I remember after the New 52 debuted and Wally was nowhere to be found, by every single comic convention at the fan question part there was at least one fan that would ask Didio "Where's Wally". Every single time.
It became a joke after awhile because it became pretty much obligatory. At one point Didio got so annoyed he said "Stop asking abut Wally already!!".
Guess he misses that and wants to go back to that. You got it Mr Didio.
