I’m not sure if the All In Saga collection in the DC Comics March 2025 trade paperback and hardcover solicitations is much of anything. Maybe I’m wrong, I haven’t read any of the issues collected, but it seems like basically a DC All In “sampler,” and that fits with the “Saga” moniker, collections of tie-in issues and indicative of not being the thing itself (see Joker War Saga and Batman: Fear State Saga).
But, seeing an All In Saga collection — and also noting that Absolute Batman hits its sixth issue in these solicitations and the end of its first story arc — tells me that in no time at all, we’re going to start seeing Absolute titles being collected; the new DC catalog arrives in March, but it wouldn’t surprise me if some of these are rush-solicited, given their popularity. And you know that Absolute (big) collections will inevitably follow; I vote Absolute Batman: The Absolute Edition, and not Absolute Absolute Batman.
