5:46:27 for start of purchase change announcements.
5:53:44 (translation starting at 5:54:10): "So right now, a majority of the lands that will be available will probably implement this lottery system but we do want to keep an eye out to see if there is a need to have even a limited area available for first come, first serve and we are still in the midst of debate for pros and cons on that matter. So I would like to actually get your feedback as well if you want to bring your input/insight on the lottery or first come, first serve basis. We would also like to take that into consideration with our continued discussion on this topic."
To me, that very much sounds like they're leaning heavily toward lottery only though they're willing to keep first come, first serve open as a limited option if players can present good arguments for why it is still needed. At the very least, they intend for the majority of wards to be lottery.
Considering all the rule changes planned, they might as well go full lottery. Existence of FCFS wards would perpetuate the botting, giving resellers an advantage in getting more plots to sell since they no doubt account for most of the botting. FCFS would also continue to leave players feeling compelled to placard camp. After, FCFS wards would potentially represent multiple purchase opportunities per lottery period while entering the lottery is a single opportunity per lottery period, and there would be nothing to prevent players from doing both. If someone got lucky on a FCFS purchase then also won the lottery, they're probably not going to regret losing 50% of their entry fee when it means they got a house in the end..
