I'm concernd and worried about some things about the sins (Spoilers for manga, and OP 3);
In the manga, we know that Greed is Greed, Envy is Envy, Lust is Lust, Gluttony is Gluttony, and Fuhrer is either pride or wrath.
That's 5/7, and leaves 2 more sins left. Pride or Wratch (Depending on with the Fuhrer is) and Sloth.
In the anime (so far) we know that Greed is Greed, Envy is Envy, Lust is Lust, Gluttony is Gluttony, and the Elric Mom (Trisha) look like is Sloth.
That leaves: Pride and Wrath.
Now, the thing I'm worried is about is the three people will "super" powers in the opening (the person with Envy, and the two people Ed and Al fight besides Greed; the one with the stretching arms, and the guy with serious Orochimaru Curse Step 2 going on). I think that the anime is starting to branch off from the manga signifficantly, even too say that the sins will be different...
Does anybody have any more info?
