Hi, here are some questions I can't manage to find accurate answers for:

>Is it possible to have every pokemons from every gen in X/Y?
As I understand we will be able to trasfer from gen5, but can we tranfer from previous gens to gen 5 then to gen 6? Basically what will be the available/unavailable pokemons?

>Are there some kind of timed events I should know about?
I think I read somewhere genIV and previous won't be able to access online play soon? Any kind of infos on things like this?

>Online play
I never tried the wifi of my 3DS yet, but can I expect to find opponents easily? Are there different types of matchs available with different tiers of pokemon (to avoid legendaries etc)? What are the bans?

>Damage type chart
I think I heard there will be a new attack/defense type chart in X/Y, it that right?

Any help getting started would be much appreciated. I am considering getting Black 2 or White 2, is that a good idea?
