What day did you order? I ordered mine March 1st. No e-mail yet.
I just received my 3500 over the weekend. It looks and feels terrific. Very well made. Wish I had realized earlier, but the meat shelf I used on my old 2014 pack doesn't work with it (I guess it didn't last year either) and I will need to make some minor changes to my load panel for it to work. Steve explained that their crib replaced the other two items (meat shelf, load panel/beavertail) in changes made to the their bags for the 2016 year I guess.
So...if anyone with the older pack needs a meat shelf or load panel/beavertail, I will make you a great deal.
I really like the ranger green color. The hip belt is comfortable, although I haven't had an opportunity to load it up with a lot of weight yet. I like some of the fine touches. I like the "strap keeper" for the load lifter straps and I really like the roll top design.
