Also, I repeat this: there are literally 0 statements of Larian about it, how can these guys up here be so sure?
They have on several occasions said that Early access will be Act 1 (ie, the description of EA on the support section of this website). While this doesn't technically mean they couldn't also add Act 2, they have not promised more than Act 1.
Given how they always have stated the early access content will be Act 1 and that with previous releases they have done Act 1 for EA. It seems reasonable to assume we're only getting Act 1. (They have indicated some intention to add more content in the EA but have not clearly defined the breadth and scope of that outside of the additional class/race options)
Sven recently said in an interview that they'd rather not make a roadmap because they did it before and then people felt betrayed when they didn't hit targets or had to remove things.
I would not recommend getting your hopes up over an Act 2 release in EA.
