Black and White recent happenings thread!

Wanted to ask this for awhile but i kept forgetting.

Is there any post game content after beating the elite four?

I know you can transfer from older gens after beating them..but is that all?

Is this game like ruby and sapphire where theres almost nothing to do but explore whats left or is it like emerald where you can go to a new place such as battle frontier? I know Online battles will be out soon, but most people are gonna beat my ass most likely because i don't bother to EV train my pokemon.
