Okay the Triple Play achievement should be live. I was going to try and be fancy, but realized I have no idea what I'm doing, so it just cycles through several collection queries and keeps a counter to see if you have a Gen 1, Gen 2, and modern equivalent of the same model. To get this you need: 
 
-M Frame, Eye Jacket, Frogskins, or O Frame 
-Gen 1 in the model or color field of at least one 
-Gen 2 in the model or color field of at least one 
-New/Collectors/Supreme in the model or color field of at least one 
 
You only need one set to get the achievement.
