Legendary Trio for Black and White?

[Jabberjaw]

Every Pokemon version has had 1 or 2 legendary trios of pokemon. Some of the trios have pokemon share similar traits, others have trios that are related through other means. So far we have had:



Gen 1 had the Legendary Birds: Articuno, Moltres, Zapdos

Gen 2 had the Legedary Beasts: Entei, Raikou, Suicune

Gen 3 had the Legendary Golems: Regirock, Regice, Registeel

And the Weather Trio: Groudon, Kyogre, Rayquaza

Gen 4 had the Lake Guardians: Uxie, Mesprit, Azelf

And the Dragon Trio: Palkia, Dialga, Giratina



So... WHAT WILL THE NEXT TRIO OF LEGENDARY POKEMON BE?
WHAT TYPES WILL THEY BE?
ANY COOL BACK STORYS YOU WOULD LIKE TO SEE?

I would like to know your thoughts it this, bulbapedia community.
