Right now, the Canon EOS 7D Mark II Body-Only is listed as "Discontinued" or is simply unavailable at several major authorized retailers.
The Canon EOS 7D Mark II, released in 2014, replaced the original EOS 7D which hit the market in 2009. So, if Canon continues with a 5-year product cycle for its 7-series cameras, we could reasonably expect a replacement some time in the next 12 months or so. But if Canon were planning on releasing an upgraded 7D in the next calendar year, why would they discontinue its predecessor possibly months before the follow-up's announcement?
Actually, there's a very logical reason why the Canon EOS 7D Mark II Body-Only has been allowed to vanish from retailer shelves; the product listing has been replaced by the Canon EOS 7D Mark II DSLR with W-E1 Wi-Fi Adapter Kit, which remains in stock at all major authorized retailers. And that makes perfect sense. All of Canon's recently released DSLRs and mirrorless cameras feature wireless connectivity, and most of the 7D II's competitors do as well. By including a W-E1 with the 7D II, Canon is basically righting a wrong, i.e., not including built-in Wi-Fi to begin with.
Of course, the W-E1 solution was never perfect (it renders one of the two available card slots useless for recording images/videos), but it does provide basic Wi-Fi camera control and image transfer when those features are desired.
So has the Canon EOS 7D Mark II officially been discontinued? No, not yet. But the body-only version without the Wi-Fi adapter seems to have been.
