It's first published in English and put online. It's static data and practically never expires. A month later they publish it in Finnish, and a month after that in French. This still shouldn't impose that the English version expires once a month. And you can't know of the translation schedules beforehand in the first place anyway. Ok, so King probably would make this interactive book in which the plot changes as a function of time, number of people killed, and whether IT really died in part two...
