Very nice! I know just how you feel. Bought my new RK two weeks ago, coming off my Heritage which i had for less than a year. It was a great bike as well but I wanted the touring frame and hard bags etc.
I picked mine last month after trading in my 2008 Super Glide. For a big bike she handles great. Its a great ride you're gonna love it. Good luck and congrats!
You're going to love it the more you ride it. So nimble and fun. One of the great things about our kings is that windshield comes off in 5 seconds once you get familiar with it. Without the shield its like a whole second bike honestly and will fix anything you might start to miss about your FXD. Congrats.
