Is DC Comics hinting at a return of the pre-Flashpoint DCU?

First we got the announcement that the the Giffen/DeMatteis versions of Booster Gold and Blue Beetle were retuning in the pages Justice League 3000. This was met with overwhelmingly positive fan reaction.

Then, on the final page of Superman: Doomed #2, we see shattered fragments of reality that are definitely not of Earth 0 in the New 52. Superman with his trunks on the outside, the 1980s Wolfman/Perez Teen Titans team in their 1980s outfits and the classic JSA, with a very pre-Crisis on Infinite Earths looking Huntress. None of the characters in the shards on this page are in their New-52 costumes.

And now we noticed that on Comixology, Booster Gold Futures End #1 is filed under the pre-Flashpoint Booster Gold series!

Booster Gold Futures End #1 is also filed this way in DC’s own web store!

While this isn’t an in-story hint, it is potentially very telling.  DC and Comixology could have easily given this Booster Gold comic a new volume. What makes this doubly interesting is that Booster Gold Futures End #1 is the first pre-Flashpoint that DC has published since the start of the New 52. Even Grant Morrison’s Batman Inc. was forced to renumber and restart with a new volume in the New 52 (and don’t even get us started on the pre-Flashpoint continuity errors that riddled that book).

It’s been rumored in the past that the New-52 Booster Gold might remember the pre-Flashpoint DCU, because he was outside the timestream when Flashpoint occurred. Is Booster Gold the key unlocking the door to DC’s past?

What do you think? Is DC hinting at the return of the pre-Flashpoint DCU?
