While one of the symptoms of my G.A.S. is perpetual lens lust, it isn't limited to lenses. I just 'invested' in some Godox lighting gear with three units and triggers earlier this year and already I'm lusting after a nice LED constant lighting system. Don't get me started on bags and cases. But as far as bodies go - well my sister-in-law loves her new Olympus mirrorless and I find myself thinking "me too, me too, I need one of those" "Our" err now my wife's D5100 works just fine but the D5600 would be so much better. And hey I have one of those D610's which the author of the article referenced by the Danno as Nikon's 'fiasco". I wonder how many new FX lens buyers the introduction of this entry level FX body brought to Nikon? Anyway, it is an entry level FX so I NEED to upgrade, maybe the new D8XX will be the cat's meow, or perhaps I should just bite the bullet and get a D5 or save a few pennies and settle for a D4 refurbished - only to upgrade to a D6 someday. And if they ever come up with an FX with the swivel screen of the D5100 - I'll jump all over it.
Unless I retire and have to learn to budget better because every Monday morning as I drag myself out of bed, I think to myself is this the week I drop the "I'm retiring on _____" letter on the CEO's desk? My GAS keeps me saying not this week. But we just amended the corporate employee policy to read "employees are expected to work until 71" - meaning 65 the old 'expected date" is now considered "early retirement". So instead of three years, I could be behind the desk another nine. .... so lots of time for that D5.
No, I'm not in my 'last camera state" - I expect there will be a new body someday in my camera bag.
Now my truck, I bought a big decked out diesel so that it would be my last truck, ... that was 2010, ... yes I've looked at the new ones ....
