Do Attached Cards follow the Swapped Monster when Creature Swap is used?
So I know my comment started this question, and if you want someone else to answer I understand. But here is why I do not think they go with the creature.
The official rules about equip cards:


  These cards give an extra effect to 
  1 face-up monster of your choice 
  (either your own or your opponent’s, 
  depending on the card). They remain 
  on the field after they are activated. 
  The Equip Spell Card affects only 
  1 monster (called the equipped 
  monster), but still occupies one of 
  your Spell &amp; Trap Card Zones. If 
  possible, place it in the zone directly 
  behind the equipped monster to 
  help you remember. If the equipped 
  monster is destroyed, flipped facedown, or removed from the field, its 
  Equip Cards are destroyed


Emphasis mine.

So it points out that Equip cards you control can in fact be on monsters your opponent controls. Creature Swap only says it gives your opponent control of the creature. Not anything else. In my mind the objects attached to the creature would still be under your control.
