Nintendo recently held its quarterly investors call, and here they confirmed a number of initiatives for the company moving forward. While calls such as these can tend to be quite long, it's been summarised in a few bullet points courtesy of Bloomberg tech reporter Yuji Nakamura on Twitter.
In his short summary Nakamura states that during the call, Nintendo president Shuntaro Furukawa confirmed that Nintendo will change its perspective on DLC content going forward, and that, similar to what we saw in The Legend of Zelda: Breath of the Wild, they're planning major DLCs for their "big" existing games.
They did not, however, mention specifically what these games were. Also, they've confirmed that the current holiday line-up has been revealed and that consumers shouldn't expect surprises in terms of further releases in November and December.
