It is most certainly a rumour to some extent, Favorite.
Due to the length of time World of Warcraft has been out there are a number of names that have been taken and the characters have simply been forgotten about or the accounts remain inactive or otherwise unplayable (i.e. closed accounts). If someone requests that a name be made available our In-Game Support staff will look into the request, depending on several factors we may or may not be able to free up the name.
If you have a name that you are hoping to use for the upcoming expansion make sure you keep it active, actually log into the character from time to time. :) If you do that it should remain available to you.
