And, that's the issue ... That you, nor DC, understand what the problem is. Shuffling a whole bunch of realities with the baggage that entails into a new line up isn't inviting. DC sales are dropping ridiculously. Them saying hey, we're bring back what you love about DC, but it's not a reboot or relaunch, we're just picking and choosing our favorite bits from pre and post crisis and the New 52 and convergence and maybe this and that from the animated universe ... It's just a turn off.
Read some of the comments from comic store owners:

Putting on blinders about the problems and challenges DC and Marvel face isn't doing anyone any favors.
I think you're misunderstanding what they're intending to do. These are still the New 52 characters, for the most part. That they are returning to their "most recognizable forms" means that, mostly, the costumes and storytelling focuses will be reverted. These are not the pre-Flashpoint characters coming back, at least not in any major way (only pre-Flashpoint Clark and that's already been established in New 52). There's a bit of massaging going on, but nothing so extreme as you're claiming that they're converging the two things (they did that already a year ago). It's basically all surface-level stuff.
Plus, each book has a Rebirth oneshot of its own. I imagine that'll cover the changes being made, if any.
And yeah, the Rebirth one-shots will cover what you need to know about the character if you didn't read any New 52.
