The main reason that non-PC platforms take a while to get the updates is because it's an external company porting Terraria to the other platforms (505 Games, in this case). Re-Logic does not do the updating for any platform other than PC/Mac/Linux, 505 Games has the publishing rights for the other platforms. The reason PC gets the updates first (and with such a long delay before they're published to the other platforms) is because it's a massive amount of work to make sure that not only have the items, mechanics, mobs, NPCs, events (etc) been correctly added to the game, they also need to function both correctly and in an accessible form for the other platforms.
