I'll always have hope that they'll eventually make it real. I just think it would be cool, and don't really understand all the hate it gets.
Because it's just too abstract. No match-ups would make sense for it. It sounds tottaly different than all the other simple types. Also, it's already a type; a sub-type. It's under normal because that's all they can or are going to do with it.
The same goes for light. Light would be a subtype of fairy, unless you're dealing with light RAYS, then it would be under fire or grass.
Basically, even though it might SEEM possible due to the moves and Pokémon, once you really THINK about it, you'll see that it's not.
