Changes in the Battle Frontier

[FreezeWarp]

It is known that HeartGold/SoulSilver will have a battle frontier, likely one very similar, if not the same, as in Platinum. What changes do you think could be made, and what changes do you want?

I really want new brains, and maybe a twist in the mechanics of each building. I also want more interesting prizes.

I'd like to see a wifi battle in each place like the battle tower has where you talk to the far right person and go into wifi and fight tons of people within the 50 rooms you get, but have this option in the other Battle places
