To be honest, I've seen a lot of the stuff written at the top on the Serebii forums in a speculative manor. So yeah, I doubt how valid they actually are.
The only generation I never played, it'll b great to finally play G/S. HeartGold is mine on release day. :D
While the names are growing on me, I can't help but think that SilverDusk/GoldDawn or GoldSky/SilverSea would of worked better.
