Shingeki no Kyojin is released monthly. I wouldn't want to guess an exact date and get your hopes up, but if someone knows, they can tell you. My best guess is probably the second week of every month (since that has been the pattern for the translators to get and release it), but yeah, take what I say with a grain of salt.

Happy new year!
