I dont think they`re going to have another deoxys event again, you can only get him by hacking or by trading with someone that has one.
Probably October 30th.
check www.pokemon.com
go to the next Nintendo event.
nobody is sure check Nintendo.com/eventsmain It is in japan from June 20th to august 31st they are giving away Regigigas in a cherish ball
I HIGHLY doubt there will be another 1 srry :-/
it's in July of 2008 but i don't know where yet.
They don't do gba events anymore they only do them for DS's
21st of August, 2012. At SM North Edsa.

There is currently no info on any future events for a Regigigas.
they havent announced one yet but if people signed the petition (which is now over) the company in America were going to hold it again on the 16th of December for Christmas
