How long before you become impatient for game to finally release?

[Burek]

I can wait as long as necessary. I usually wait a few months after the game is released to buy it, when I find it at a decent discount.
Witcher looks interesting, and after I found out it has a Casual difficulty, I decided to pick it up, whenever I can find it under 25€.
20-25€ is my upper limit for any game.
