As of my last update in October 2023, there are no official announcements regarding future Wi-Fi events for Pokémon Black and White 2. These games are part of an older generation, and official events for them have become increasingly rare. For the most current information, it's best to check the official Pokémon website or community forums.
there will be a next event on pokemon black and white
Its event is already over. Darkrai's event is going on right now at May 9th.
It's actually called Meloetta, and apparently is an event Pokemon, and can't be found in the game without hacking or going to an event. The event is probably more safer to go to gamewise, or you'll waste an hour trying to hack into your Pokemon black/white.
meloda is an event pokemon, the date of the event is unknown
You can get Zoroark by trading an Event shiny beast Pokemon to Pokemon Black and White via the Relocator.
There is not an event to get Keldo YET.

You can't. You have to get Victini with an event.
I have Pokemon Black, and as far as i know you cannot catch event legendarys without an event (eg. Genocect, Zorua). You cannot catch some Pokemon on the game, but Pokemon White can, and White can't catch some Pokemon that you can catch on Pokemon White. Lol!
