Just a few I could think of:
General technological stagnation. Not enough improvements in the manner in which games are made. Games continue to increase in size, but older tool chains can't support the weight, and they can't improve much because the hardware couldn't handle the tech improvements. Devs spend more time and money squeezing blood from the stone, and less time on the actual game.
Playerbase loses interest in the product, due to the platforms becoming old hat or too commonplace. Consumer interest moves on to newer, more exciting frontiers. This happened a bit last gen when some people got tired of PS3/360 being old and busted, so they moved to PC.
Some aspects of hardware could actually begin to cost manufacturers more to produce than newer alternatives. See stuff like DDR3/GDDR5 vs future DDR4 improvements and upcoming stacked/HBM chips.
Marketing deals and stuff start to dry up because those with the money won't see any potential growth in the platform they are being asked to invest in.
There are some reasons why they cant move to PS5/Xbox Two too.
Releasing a big platform is a huge risk and investment, Sony is on the best postion to release a PS5, but why would they? they are selling, they are on top right now, only a few of their games have been released, with more to come, the system doesnt even have its first ND game yet!
And thats other thing, developing games is taking longer, less "true" next generation games are released, and more HD ports are made for fans, this is because they become too much of a risk, and sometimes they are even delayed.
People getting bored of the tech its not always true as the 360 got its best years thanks to Kinect, the system got a second life, even if short, new systems take long to develop and market, thats why 360 and Ps3 were not replaced earlier.
Now, Microsoft and Nintendo have more of a reason to upgrade, MS struggled with the ONE at first, but they are aggressive enough to stay competitive, the Xbox brand is still important to them.
Nintendo has the best reason reason to upgrade, the Wii U was a disaster, and sales are poor,for a time people were actually demanding for them to drop their system, but they didnt, they cant abandon their system wich was a huge project and release another, more powerful console because that is simply going to take years to develop. Wii U is going to have a "normal" console cycle.
The PS4 is just starting, im not sure a short cycle is even realistic anymore, if anything the era of short dev. cycles could be over.
