Diamond Previews list of product changes for June 7 states that "Wonder Woman Vol. 9: Resurrection HC (MAY160327, $24.99) has been increased to 176 pages and now collects issues #48-#52 and Wonder Woman: Rebirth #1."
This means that Wonder Woman Vol. 9 now collects the last five issues of Meredith Finch's run, and then the Wonder Woman: Rebirth special by Greg Rucka.
I guess if there was still any concern that the "Rebirth" event was a reboot, this would assure you that continuity stays intact, because apparently Finch's final pre-"Rebirth" issues lead right into Rucka's Rebirth special, sufficient to collect them together. And maybe Rucka's Rebirth special wraps up Finch's run sufficiently enough that it's more proper to collect it at the end of Finch's run than at the beginning of Rucka's.
But first, I'm very, very surprised that anything with even a hint of "Rebirth" to it wouldn't be collected in brand new, newly-numbered trades, marking sharp division between the old and the new.
Second, this of course means that if you were a trade-waiter, hadn't been reading Wonder Woman, and wanted to start with Rucka's run, you'd either have to buy the final collection of Finch's run to get every piece of Rucka's, or you'll have to pick up the Wonder Woman: Rebirth special separately.
This is unexpected; I'm curious to see if any other trades follow suit.
