As we noted last night, The Rock was indeed in New Orleans for the Hall of Fame ceremony, and he noted on Twitter that he "missed you New Orleans." A photo of him, Steve Austin, Lilian Garcia and Jim Ross can be seen at this link.
According to F4WOnline.com, Rock was rehearsing something that will be taking place at WrestleMania 30, but exactly what that is remains unknown.
PWInsider.com is also reporting that The Rock is expected to make an appearance on the PPV tonight, and will be involved in "something special" during the big event.
