Hi, coffee (nice choice of username, by the way)! I'm afraid I'll have to be honest and say that as of right now, there is unfortunately no concrete schedule or timeframe for when the Wiki will be up and running for v4.88. There are still a few obstructions in the way before the update process can start in earnest, and there is in practice no real editor team working on it right now so any efforts before then will be rather ad hoc until a plan is put up.
I'll update the front page as soon as there are any news on that front, so please stay tuned!
