This is sort of a way to work around the increase in costs over HD development. Although some companies seem to be increasing it to justify continued development. Stockholders want more profit, and they invest so the company can keep making games, so their role is very important.
Gaming isn't government funded, and will probably never be in its current form.
If you want gaming to continue to become more graphically complex there is the fact that prices have to increase in some ways. The cost of developments goes up, and as a results the profit needs to be sustained by higher prices and DLC.
DLC is just another way of increasing the price without upsetting the consumers too much. Maybe we need to reevaluate this rule that games need to still get more graphically complex, even though results are diminishing for most people's perceptions, and that you can achieve great entertainment with less graphics. The processing power hasn't been a huge barrier to gameplay since last generation.
