I'm not entirely sure where it says "this is what it'll be like for three years,"
Because it doesn't say it *will* be anywhere. It has been since the Heinboot. The "new" status quo established by this issue is very nearly precisely the same status quo that Gail inherited when she took over the title. Read the thread Nev started um... downthread, I think? I do this whole steakhouse metaphor, it's fun. I fully appreciate that people who didn't live through the monthly (or multi-monthly in the slow-ass case of Heinberg) pre-Gail v3 have far less reason to loathe this plot point than I, but personally I've more than reached saturation with a Diana who has no part in and accepts no responsibility for her gods or her people.
I think Jason Todd, his trophy case, and those who angst in its vicinity would beg to differ, though.
Eh, Jason's death was never central to Bruce. Jason didn't even exist until 1983, and at the time he died he'd been around for approximately 10% of Batman's history (well, roughly five years in roughly forty-nine). The relevant switch in Bruce's psychological makeup, really, was from "guy who doesn't want another kid to hurt like he did" to "guy who wants to avenge the hurt done to him." Jason's a convenient prop, but ultimately incidental, a way to bring the already-conceived DKR Batman plausibly into contemporary canon and stir up the fanbase with Big Event bait. His interactions with subsequent Robins and the sheer volume of his non-Jason-related crazy kept DitF from being thematically meaningful long before they ever dreamed of returning him to life. But you'll never find an adaptation where Bruce's parents weren't shot down in front of him, or, more on topic, a Wonder Woman not created by the gods (though the DCAU Diana has the skeleton of the story - divine genesis - without the heart - the mission - which is the #1 reason the DCAU Diana doesn't work).
