Hey there,
Thanks for writing to Wikia. That's an open question right now, actually. Although we want to implement something similar, we have to scope that implementation pretty thoroughly.
When we make a decision, we'll be sure to tell everyone loud and clear. Sorry I don't have a better answer for you right now!

I guess I'd be happy enough to create my own map, upload an image of a map and then pin it from there. Getting the old data would be nice too so I'll look into that. I'll probably just wait though since they may come up with something. I'd rather not have to create and fill out maps more than I have to.
