In this case, then yeah you can wait until Easter. I'm quite sure that they can release Natsuki's patch by Easter if all goess well, or if not then at least Rikka's route should be a good read by then.
Anyway, today we have surprise release of Rikka's patch in which it's very surprising because they say that they may not be able to have Christmas release, and lo and behold they managed to release it one day before Christmas. Go get the patch here, and enjoy the Christmas gift there. As for the next plan, Trip will took a rest for one or two weeks presumeably for holiday so perhaps we'll going to see the progress at Touko's route at 2019 later. Here's this week update below, even though you may already see it:
Common: 100.0%
Sora: 0.0%
Marika: 100.0%
Natsuki: 0.0%
Misa: 100.0%
Rikka: 100.0%
Touko: 0.0%
Total: 54.06%
That's all for this week update, and merry early Christmas.
