The only way I can see them having another title is for it to be a gimmick title (TV or Hardcore) and for it to be shared between ECW and Smackdown. For the life of me, I don't see why everyone likes the Cruiserweight title as its nothing compared to what WCW's used to be, and it limits you to the # of people that can compete, when a TV title (hopefully with the "defended at all times when you're on the air, but not outside of it, and falls don't count anywhere" rule so as to get rid of the pure comedy that the Hardcore title had the last time) for all intents and purposes can give you large combinations of participants. Someone like Tommy Dreamer wouldn't fit in a Cruiserweight title chase, but he could be fine with the TV title, as could Mark Henry or Chavo or the Miz or whatever.
I'd love to see that happen...the TV title...but only if they balance out the rosters the correct way AND they focus more on the tag team titles, so it would be a little hard when Creative doesn't know what to do most of the time.
