Nobody, and neither did I. All I said was not to get too attached, due to the implied kill-fest and the fact that the character doesn't seem to be mentioned in any of the solicits coming out of the crossover. In a darkened DCnU with an crossover like this one, character death (likely to underscore the severity of the situation) is pretty low hanging fruit. Coming out of the Culling, current evidence would suggest that she's either dead (killed either in the culling or the inevitable escape) or inactive for some other reason (survived but not appearing prominently after the crossoever).
