Preference for a well-specced 7D Mk. II with APS-C sensor is certainly not only an "individual preference" but definitely on the wishlist of quite a few people in this forum and many more outside of it.
BUT:
Both Canon (and Nikon) have delayed introduction of successors for their hi-end APS-C DSLRs for a very long time (Canon 4+ years, Nikon 3+ years)
AND
meanwhile FF-DSLRs (6D, D6100/610), mirrorless FF cameras (Sony A7/R) are now available in the same price-bracket that a 7D II (or Nikon D400) would likely be launched into (USD/€ 1500-2000+) the target audience for a 7D has shrunk considerably. Especially "general use" enthusiasts and semi-pros on a budget are not waiting for the 7D II as much as they have waited for the 7D (when FF bodies were still considerably more expensive). By now, many Nikon D300/s users have moved on to D800 and (less so) to D600/610. Many Canon 7D users who never or only rarely experience focal length limited situations have moved on to 6D or 5D III. Or are seriously considering smaller/lighter (FF) mirrorless options (e.g. myself ... and no, I am not the only one with such an individual preference).
From my observation, target group for 7D II by now are mainly "action + reach-oriented "semi-pro/enthusiasts" and possibly some semi/pros who don't want to/cannot afford two 1D X bodies. However, this group is still large enough to warrant a 7D II, especially as long as Canon brings no higher MP / higher fps FF DSLR [5D IV] to market.
That's why I believe Canon will bring a 7D II rather soon in 2014 and a 5D IV only later (2015).
In addition to action-oriented/reach-limited users they will certainly also try to attract some video shooters on a budget lower than 5D III. Plus some "generalists / enthusiasts" who are happy with an (improved) APS-C sensor and willing to pay for a better body than 70D ... AND don't want to spend large sums to replace their existing EF-S lenses in order to go FF. Especially 10-22, 17-55, 15-85, 18-135 STM, 60 Macro ... these are very decent to really good lenses and to replayce them with equally good or better EF (L) glass ain't cheap. 100 L Macro, 24-105, 16-35 II or 24-70 II ... $$$-$$$$
