littleman,
It happens.. you could get a five inch thick resonding affidavit. It depends on the issues at hand and whether there are any other issues respondent may bring up that are relevant to the case.
If you really want the motion to go ahead, I suggest you be prepared for a large responding affidavit and get ready to review the entire thing and prepare a reply. Hopefully though, the responding party won't bring up any new issues.
