Looking at the two notices and putting two and two together, logic dictates that phase 4 (which will be the open beta) should begin on August the 17th. Of course itís not mentioned explicitly, so for now weíll have to handle it as a hot rumor.
That said, letís hope to hear an official announcement soon. If the August the 17th date proves to be true, the open beta phase will be extremely short. Preorder slips state that early access will last seven days. Considering that the game will release on August the 27th, three days of open beta seem a little on the brief side.

Your characters are supposed to carry over into early access and then the game from what I heard, but if they release it that late, it is no longer a beta... it is early, early access/demo not beta.
But it also says "registration" not until that date, which doesn't necessarily mean the beta starts that date. They could do a week of people who already have codes, then open it up to people that didn't sign up before the 22nd.
