While I wish it was sooner, my big concern will be not knowing for the next 5 months if you will get a C&D. I wish you could release the patch to someone seemingly untrustworthy that could be expected to leak it regardless of the legality of the patch, though that's no help since it would either be leaked immediately or the person wouldn't be provably untrustworthy. lol.
I hope it goes well.
EDIT: For the people asking about additional testers, I would assume a lot of the work is formatting and inserting text. So the "bottleneck" is the people able to do that. Even if Sky wouldn't have to waste much time to teach new people how to insert the text, you still might have a big problem with "version control" and quality control.
Even a bunch of additional bilingual testers might make only a minor impact on the release date, since Sky would still have to "train" them and someone would have to monitor and organize their input. I could see things changing if someone disappears, though, as is common with fan/internet projects.
