Sounds cool. I still am very wary of DC when it comes to Wally but I'm hoping as well that at least one out of the multiple stories in this oversized issue will feature Wally.
Maybe even Bart as well.
Also I'm looking forward to the different variant covers through the decades. Especially the 90s one of course which should have Wally on it. The artist on it is also very good.
Since it's an anniversary issue the story with Wally, if there is one, will most likely be one from the past so I wouldn't worry about it.
And if its not a past story I'm really hoping this is true and well have our real Wally back and the HIC atrocity will be erased.
