We already know that Pokemon 8 is due out this year. Nintendo and The Pokemon Company have both reiterated this multiple times. However, the announcement may be coming as early as next week, according to a leaker who has a history of leaking Nintendo related things mostly accurately.
NintendoSoup points out that Twitter user @muguwus, who previously managed to leak the entire contents of the Nintendo Direct broadcast last week with almost total accuracy (see images below to see their tweets that did so), has now taken to pointing out that a Pokemon announcement is coming “soon”.
So why next week? Next week is “Pokemon Day”, the colloquial name used for February 27, which marks the release of Pokemon Red and Green in Japan in 1996. The Pokemon Company has used the day to make new announcements previously—Pokemon Sun and Moon were originally announced on this day, for example. Thus, there is the expectation that Pokemon 8 might be announced next week, too.
If it is, it would only serve to add to the already ridiculously swollen Nintendo Switch lineup for 2019–but in the end, nothing has the power that Pokemon does, so I think even with everything else, we all could do with our first look at the first mainline console games in the Pokemon franchise.
