It looks that way as WWE is now advertising that the July 18th PPV is titled "Money In The Bank". Also, they have April 25 PPV listed as "Extreme Rules" while the May 23rd show is now being called "WWE Wild Card". A new show called "Fatal Four Way" is slated for June 20.
There has been talk around the company for months about coming up with new concepts around which to sell the shows. While I will miss the MITB match at WrestleMania, it does make sense to build a PPV around it later in the year and then have the winner use his match to push SummerSlam, much the way that the Royal Rumble winner has done with WrestleMania.
