According to a solicitation on Penguin/Random House's wholesaler website, Bruce Wayne and Selina Kyle will indeed go through with their wedding - or at least part of it anyway.
The solicitation, for a trade paperback collecting the not yet solicited Batman #51-56, leaves no question whether Batman and Catwoman have a wedding. Taken at face value (see below) it appears the nuptials actually take place, but given this is comic books the copy leaves some wiggle room as to if they actually marry, making a last minute twist still a possibility.
The wedding is scheduled to take place in July's Batman #50.
The title of the trade, "Cold Days," could suggest a visit from Mr. Freeze is in Batman's future as well.
Here's the full text from Penguin/Random House's solicitation, along with the placeholder cover image:
