I've been in a similar crummy situation, having to wait on access to dlc that others were already engaged in. Not a winning scenario by any stretch of the imagination (despite what the game developers tell themselves).
I did get access to Jaws of Hakkon the day that it became available, and for those who were forced to wait and yet still intend to purchase the dlc; it is worth the money and the wait.
That being said, I will be enjoying the Witcher 3 while you are heading towards the Frostback Basin, so I probably should have just kept my mouth shut?
