Roseus Centre... okay. Aromatisse and Budew confirmed so far.
Also 3DS version gets the Delibird Escalation battles. Have fun raking in items!
EDIT: Okay most of these new stages look to be pretty rubbish in design and make Albens Town look tame. Yay Machop... >_>
DOUBLE EDIT: Oh and the 3DS also gets Manectite competition now. Will probably do an attempt when I get more hearts because most of these new stages are terrible hahaha.
TRIPLE EDIT: Apparently:
Budew: Base 40 Grass w/ Mega Boost+
Machop: Base 50 Fighting w/ Pummel
Shinx: Base 30 Electric w/ Counterattack
Whismur: Base 30 Normal w/ Paralyse
Luxio: Base 50 Electric w/ Block Smash
Spritzee: Base 50 Fairy w/ Mega Boost+
Machoke: Base 60 Fighting w/ Stabilise
Roselia: Base 60 Grass w/ Rock Break
Aromatisse: Base 60 Fairy w/ Power of 4
Roserade: Base 70 Grass w/ Stabilise+
Pastebin
Spritzee would have looked very good out of that bunch if Gardevoir did not Mega Evolve so fast hahaha and Roserade is decent.
