When I first heard them, I thought the names were a joke, and hoped they weren't final. xD;
Now I've gotten used to them, so they're okay.
I think the 'Heart and Soul' concept is neat, yet for some reason when you put 'Gold and Silver' after them, it still sounds a bit lame, in my opinion.
Should have just been Pokemon Soul and Pokemon Heart.
I think that they should have done what they did with fr lg and name it something that has to do with the game or keep on going with the gem theme
The titles actually do have a relation to the game as Heart has been referred to Ho-Oh before, and Soul has been referred to Lugia as well.
