Nice idea. I wish you good luck with not spoiling the fun for yourself. It's only a week now, so it should't be that difficult anymore.I have a similar situation at the moment, although it isn't that much self-imposed. I can probably play the game after 25th of June. 
Since I have to study in the meantime. In about three weeks I have exams and after that I need to finish up some projects. After the release I will only install my CE and see if my laptop can handle it. But I'm sure it will be worth the wait and the longer I have to wait, the better it is going to be. It's going to be quite difficult though not to read the spoilers on the forums and in the media. But on the other hand I now have enough time to re-read the books again.Btw if you purchase the The Witcher now on GOG.com, you will get a nice calender to count the days down.Good luck witcher!
