In black and white all events have been closed down since x and y came out

Answer 1

There doesn't seem to be any new Pokemon events coming for Pokemon Black/White since it's getting old. All the new Pokemon events will be for Pokemon X/Y. The current Pokemon event for X/Y is the Speed Boost Torchic with the Blazikenite.
Here is a link for all the Pokemon events for Black/White: http://www.serebii.net/blackwhite/wifievents.shtml
As you can see there hasn't been any new events since the Darkrai WiFi event.

Answer 2

The next event to come is the Celebi event in X and Y.If you get access to Pokemon Bank until 30th of September 2014 you will receive this Celebi.
