You're not alone. I pretty much zero idea where anyone is getting this from. Some people on here are talking about a reboot, but that makes so little sense given the fact that Jim Lee himself felt the need to let everyone know that there isn't a reboot coming. And this was said when Bendis and Synder were already signed on.
You want my opinion? DC's been planing this identity reveal for a while now. It seems like it's a new direction that they've been interested in taking Clark for a while regardless of lawsuits. Their first attempt didn't work out primarily due to the things surrounding it like the aesthetic, the marketing for the story, and the story itself. But that doesn't really stop them from doing it again, does it?
Want an example of them failing with an idea and then succeeding once they try it again very shortly after? Jon Kent. Yup. People forget but DC created the biological son of Superman and Lois Lane for continuity back in the New 52 in the form of Jon Lane Kent. He failed pretty hard, but then a few short years after his death Jon Sam Kent was made, and he's been a great success.
They just switched up the approach. The same seems true here. And if Jon Sam Kent can be the success he's been despite the failure of his previous incarnation, then there's no real reason to think this can't turn out far better than Truth. And what's funny is that both ideas break rules of Superman. Similar to how Clark getting married or telling Lois his identity had rules against them.
