I do wish people would stop stating 'facts' which are just to prove a point
The original 1D was realeased in 2001 with APS-H and the APS-H sensored 1Dx has continued to date - 11 years without a break.
well, it seems necessary to establish the facts here: the last and final APS-H camera (Canon EOS 1D Mk. IV) was introduced in October 2009. So the APS-H line of digital cameras has ended a mere 8 years after its introduction in September 2011 (Canon EOS 1D).
Speculation: APS-C will most likely be around for another 20 years or so.
Reason: Both APS-C and APS-H sesnor formats were originally introduced because 135 format ("FF") imaging sensors were "too expensive" and or technically to challenging to produce in mass-market quantities. By now, "FF"-sensors can be manufcatered rather cheap, although Canon tries to still charge huge premiums for that sensor format. APS-H has turned out to be too close to "FF" to be continued on its own merit. This was clear from the start and therefore Canon has never even bothered to develop APS-H specific lenses. After 8 years Canon finally pulled the plug on APS-H and decided to move to only 2 sensor sizes in its DSLRs like all its competitors in the market. Better synergies of scale=more profit.
AS opposed to APS-H, APS-C does bring large enough photograhic advantages compared to both "FF" and smaller sensor formats as well. Super Teles are expensive and there are quit a number of reach-limited photographic applications. Furthermore, "walk-around" and wide-angle lenses can be built significantly more compact, lighter and at significantly lower cost compared to FF-lenses. Part of these savings are passed on to attract lower-budget customers while the larger part of these savings is pocketed by the Canon (and the other makers) = more sales AND more profit. This is why APS-C is going to stay around for a while. This will continue with mirrorless digital interchangeable lens cameras: mFT ... too small, advantage in lens size not convincing vs. APS-C ... so APS-C will win. FF will be reserved for the "top segment". History repeats itself.
