Nothing wrong with asking questions.
I can't comment on the quarterly shipping savings. I thought I read that it's about a $20 savings per shipping period, but I don't want to say with certainty. Hopefully someone else can give a firm answer for that one.
As for the confirmed figures:
MODULOK (not Mantenna as I first stated)
Squeeze or Tung Lashor (one or the other)
Scorpia (strongly hinted but not confirmed)
Blade (his swords were in the display at SDCC, strongly hinted but not confirmed)
