I wouldn't recommend trusting Larian on this information.
It's not that the company lies or misleads, it's that they WANT it to be true then things happen and unfortunately it decimates a small companies ability to deliver (look at the music, their composer was taken ill and wham! they couldn't compose new songs for the game).
If they come in August, great, but if you really don't replay computer games you should wait 5-10 years for the finished version.
