Realistically, this is not feasible. Unless the weapon you're trying to unsheath no longer than the length of your forearm (see: Daggers), you'd have such a hard time getting your weapon(s) out of its(their) scabbard(s), you'd be impaled before you got anywhere near ready to do battle.
That being said, in a world where giant dragons fly around using magic, there exist talking lizards, cats, big green people, elves, the ability to kill with your voice, and so many more, I'd like the back-scabbard way more than I'd like one weapon being unsheathed, while your off-handed weapon teleports from hammerspace into your left hand.
Shields on back, too. I know my arm would be damn tired if I had a big hunk of metal/wood/hide/demonic material constantly attacked to it.
