For the record, it actually took them about 6 months to patch Maka Wuhu. Also, they didn't even add a fence; they just fixed Lakitu (so you still had people trying to do the glitch after the patch to hilarious results).
That said, S0L said he was told that it's going to come in some hours. Either way it should be soon.
