Probably gonna need ot wait till after Xmas sales or new years for antoher offer I'd guess. But at this point, if you can, might as well wait and see if we get the new one early next year.
Don't buy a current-gen unless you really need one right now. The next-gen Apple TV's was *supposed* to come out 4-6 weeks, ago, so I assume we're just a month or two away from it's launch: https://www.macrumors.com/roundup/apple-tv/
