There's no word of a patch, and it's probably best not to get your hopes up. Also - spoiler alert.
Alright, so spoiler warning here folks - we're going to talk about things that happen in 'Skyward Sword' because the glitch in the game can't be talked about otherwise. You've been warned!
The way Nintendo explains it, this glitch renders the game unable to be finished. The company has issued full details on how the glitch happens so that you don't end up doing it in your copy of the game, but there's no plan to fix the game via patch. The details of how to cause the glitch are below.
1. At the beginning of the quest, go to Lanayru Desert to retrieve the song of the Thunder Dragon.
2. In the Lanayru Mine, speak with Golo the Goron.
3. Complete the Thunder Dragon's event, and receive his song.
4. Before heading to the forest or volcano regions, speak with Golo in the mine again.
5. At this point, the forest and volcano events will no longer occur, making it impossible to continue.
