question concerning interaction between chapter 1 and chapter 2 players

I know it's kind of early for this, but when chapter 2 comes out, how will we be able to interact with players who have chapter 1 only? For example, i know chapter 2 will have tons of new weapons, will they be tradeable to chapter 1 characters?

I'd like to know if:

Can Ritualists and Assassins play through the Chapter 1 storyline?
Can Ri or A sub profs be given to Ch. 1 characters through Desert quests, if you've bought chapter 2?
Will characters you transfer from Ch 1 to Ch 2 be able to move freely between both storylines?

Things like that. I'm sure the answers have been given, but I'm not up on what the Frog, Gaile, whoever has said.

i'm 99% sure all 3 answers to that are 'yes' as long as u have both ch 1 and ch 2

It's too early to be asking specific questions. Closed.
