I second ATV's. (I'm utterly boggled as to why some of the local yoohoos fire up their ATV's to hunt the back 40's. Just turning the key alerts every deer on the farm.)
Nylon leaves to stick on your clothes and treestand. (People buy these?!)
Backpacks and slings to carry your bow, and as I've seen, to carry other packs. (Again...?)
"Still Steamin' Buck...Ummmm, yeah. (As if buck urine isn't disgusting enough.)
Deer calls I saw mentioned on another post, called a buck "growl" and buck "roar". (I suppose a buck bugle, buck belch, and buck trumpet will follow. I envision the buck trumpet as an 8-foot tube of 6-inch plastic to replicate an elephant's instrument, with an air horn to blast into it. Mark my words, look for it next year.)
The current rage of tent blinds. (I admit, they sure look pretty all camoed up and shiny with their broad flat surfaces. Though I can't help but notice their catchy, light reflective nylon gleaming across vast fields, I still have a funny preference for unassuming, natural brush and log blinds.)
