I also believe it's a new type, but I think it'll be something more related to fairies than love. Love is too specific, but fairy already fits a handful of Pokemon and moves. Also its german name is a pun on fairy.
A bigger Eevee is off the list due to Shiny Flareon being exactly that. Anything like it would be too similar. But they can still go with pink. And we have plenty of pink normal types.
No! Shiny Flareon is not a bigger Eevee because it's a Fire-type. Plus, they can make a brown Eeveelution with a noticeably different design than Shiny Flareon, or change Flareon's shiny a tad. They've already changed Flareon's design a bit in Gen III. Its secondary color is now brownish instead of yellow.
We know it won't be flying, flying doesn't resist itself
Completely meaningless. Patterns have been broken before. Most famously third versions.
Why do I have to move with the crowd of kids that hardly notice I'm around? I work myself to death just to fit in.
