10km egg

That is a good question. I'd guess no as when other baby pokemon came along, they replaced them with their baby evolutions (ie hatching pichu, wynaut, azuril, budew, magby, elekid, smoochum). that and it would let niantic move more pokemon to the 7k eggs.

Agree with MetagrossMaxis, probably not since that's what happened to all other species that got a baby added.

Nope.

I just hope that the cost for a second move will stay at 25c/10,000s for Munchlax by the time I finally hatch one.
