the events will roll around next year again (well except for the lightning returns and dragon quest events), and there will be new items added to the events each year an the old will be there as well. on the new years event, only the horse helmets were for this year, all the other helemts like the snake an the dragon an the rabbit were from previous years, same thing with the xmas event, the reindeer costume was from the last year in 1.0, etc etc. they did it like this in ffxi also
