One other addendum that I postulated for S-4:MB has TWO audiences: his main core, and the spoiler audience. MB attempts to entertain and surprise his main audience, while misdirecting us, his spoiler audience.
With people expecting a swap, it would be a "surprise" NOT to swap them. It would also be entertaining to swap them according to gold/silver torches.
It definitely messes with our spoiler heads though, as you can see the time and bandwidth being used to debate this issue.
P.S. I'm not saying ABSOLUTELY that there will be no swap (and some of you, IMHO, seem to be thinking that I'm saying that). I'm just inclined against it right now. There is still plenty of reasons why, and evidence that, a swap can and will occur.
