The mystery is always more interesting than the reveal, and the truth behind the Joker BEFORE the skin-bleaching vat is probably a lot less interesting than the possibilities. To many of us, we consider the character's real birth to be at the moment of change, not before. The same way that Bruce Wayne really did die with his parents on that street as a child, replaced by the new creature called Batman.
I personally like the mystery and the conflicting stories, but then again I'm happy for writers to attempt to tackle a character's origin if it casts some original light on the character's personality and motivation. Alan Moore did it well, in a way that makes sense and outlines the parallels between the two characters. But if its just a marketing gimmick, or if its just written in for the sake of having an origin to please some pedantic fans, its worthless. Whatever they come up with for Confidential, it won't change the fundamental form of the character since his pre-vat origin is NOT a vital part of his character. Batman's parents HAVE to be shot in a pointless mugging, Superman HAS to be a farmboy orphan whose planet was destroyed. Change these parts and they cease to be the same character. Joker can get his smile, skin and hair from anywhere, he's still the Joker.
I'm happy for DC to do it again a different way if there's a POINT to it in the context of the story besides boosting sales. Either way, is it really that much of a deal? This'll only be 'official' until the next character revamp or history changing event anyway. Its all stories, and if it makes sense in the context of its own story its all good.
The character is made of ALL of the parts shown to us in the comics (and tv shows and films), not just whatever DC has deemed to be 'official continuity' for this month. The Joker is a zany loony toon, a harmless trickster, an antisocial homicidal maniac, a technological genius, a comedian, a pathetic loser, a vicious gangster, and a criminal mastermind all at once. He's cesar romero, jack nicholson, mark hamill, and heath ledger rolled into one. He's a grin with white makeup and a laugh, born from a culture which fears chaos, demands celebrity, and embraces the mythic.
damn got off topic. But yeah I'll be reading it with interest and an open mind... There's no reason not to
