It's your money and your decision honestly. BUT with the game releasing two months later you will have more time to play those games that you will buy during the steam sale and also save up those 60 Euro again. I would not worry about Cyberpunk being a Star Citizen like game. The Witcher 3 has also been delayed a couple of times and see how that ended up. But at the end of the day it is your money and your choice of games you wish to play and support.
