New information on Pokemon Sun and Pokemon Moon will be coming on August 1.
New Pokemon Sun and Moon information has been coming in pretty regularly. Earlier this week, The Pokemon Company released a trailer showcasing six new Pokemon that will be making their way to Pokemon Sun and Moon, along with a press release detailing the new monsters. It was also revealed that the new games will allow for Hyper Training Pokemon that have reached Level 100, while the Global Link will shut down in October in order to be updated for Sun and Moon.
The next announcement will be coming in early August - the earliest of August, in fact. On August 1, more information will be revealed about the titles according to the Japanese website (via Siliconera). This will take place at 22:00 Japanese Standard Time (9am ET/6am PT). There's no indication of what information will actually be shared, so start speculating!
Pokemon Sun and Moon are set to release November 18.
