I think they will. Looks like Pokebeach's leaker got the names flip flopped, so their evos should be Espurr. Although, I wonder if they'll have one similar looking evo though, or what exactly will happen with their differences.
Sweet, I hope so. Haven't been following the rumours/leaks so Espurr is news to me.
I think this is going to be like the Nidoran scenario. If there's only one name for the evos then maybe they'll just keep their names the same while being differentiated solely by gender, though.
