I hope they have Susan back. Seinfeld isn't as funny without her. Someone else in this newsgroup brought it up: George should wake up from a dream and find Susan by his side...but that should only happen in the middle of the next season. George will begin to miss her and become really depressed to the point where he will want to give up and maybe kill himself?? and then he'll wake up and BAM! there she is...
It's worth a shot
