when the book release date was announced before SWGE dates I thought, wow we are going to get so many details before the land even opens.

I wonder if it will impact sale books because it's coming out only days before SWGE at WDW and well after DL opening?
I have read a couple of SW books but can't say I have all of them. I'm sure the avid reader will still buy it no matter what
Then will we say the book is better than the land?
