When does the Alpha Test end?

[Orophin]

And If I get this correct When they say if there's demand for Alpha to be up after Alpha testing is done... does that mean anyone who hasn't tried it yet can see what Alpha is like? meh

It's probably just like the demand to keep playing 1.0 after the story officially ended. If they let people in after the test phase is complete, (aka they stop taking bug reports) it'll be just to check things out.
