Here's what Wookieepedia has to say on the whole Korriban/Moraband affair.

Korriban appears in the final episodes of Star Wars: The Clone Wars. George Lucas preferred the name "Moraband" to Korriban during story development, leading the episode "Sacrifice" to refer to the planet as Moraband. The episode guide's trivia gallery clarified the issue, stating that Korriban has had multiple names throughout its history. As Korriban is referred to as such in material that is later in terms of in-universe chronology, this article retains the planet's name of Korriban.

So "officially", Korriban and Moraband are both valid in-universe designations for the planet. That means everyone devotedly married to "Korriban" don't have to complain about "Moraband" anymore.

Of course, I don't care either way. It's the people behind-the-scenes' continued obsession with trying to fit square pegs in round holes that's pissing me off; the current incarnation of the EU IS NOT CANON and is ON IT'S WAY OUT -- GET OVER THE MOTHERFUCKING RETCONNING ALREADY!!!
