Non sequitur.they will end up encompassing another demographic, selling more cameras.
"Encompasing another demographic" does not mean "selling more cameras". It may as well mean "selling less cameras".
The "features" would sell more to a marginal demographic. The time and money spent on extra R&D would sell less to the core demographic. Are the gains in the former are worth the losses in the latter? It depends, but considering that the market is competitive but still segmented and Canon is still its leader, I won't be surprised to know that they aren't.But they must have the will to do the R&D to make it happen and include the features in the first place. In the long run, if they invest in the development, these features will sell more cameras, not less.
