This is a bit of a weird day for the franchise as I'm not really sure how to feel. KW will obviously still be around, but won't have as much of his hand in the day-to-day stuff. I have to say though, I'm really looking forward to and excited about turning the page on KW's tenure as GM and the beginning of a new era.
And for those saying KW will still have control over decisions, I'd suggest you guess again. Hahn has had a number of opportunities for other jobs and other interviews. If he didn't think he was getting full control as GM, he wouldn't be here.
