Nintendo is springing another press event on us, this Friday, October 21 at 8PM (7AM EDT). The pre-recorded presentation will be streamed online, and will focus on the upcoming November firmware update for 3DS, along with details about Mario Kart 7's wireless functions (probably referring to online play).

Those two things alone don't seem like much for a press conference, so either this thing will be mercifully brief or there will be some surprises. There might be more to this firmware update than video recording. Maybe.

[Thanks, Dali!]
