It’s very old now since it’s been posted in January of this year, but one of the translators mentioned that “We’re hoping to try and have most (if not all) the answer arcs released by the end of this year.” Since it’s been so long, it’s subject to change since then but it’s still something.
Fortunately the remaining chapters for Higurashi has already had TLC (Which I believe stands for Translation Checking in this context) and editing has been completed for months now.
The status of Higurashi, Umineko, and Golden Fantasia and the weird way on how they’re being worked on was also answered there on March.
"There’s a few different reasons. The work currently been done on Higurashi for the answer arcs is a little different than usual, so our standard weekly updates wouldn’t convey its state of progress. In the case of Umineko, we’re working directly with Witch Hunt, an independent group, so once again, it’s status is rather different from normal projects.
As for Golden Fantasia, the Umineko Fighter, there aren’t any status updates at the moment because we’re focused first on the programming aspect and making sure all of the gameplay elements will function properly, especially in terms of enabling netplay. Those goalposts have somewhat nebulous timelines, so again it’s hard to report at the moment.
I can say work is definitely being done on all three right now, and we hope to have them released as soon as reasonably possible with hurting quality."
That’s probably just a typo at end and the intention is “without hurting quality”.
