Is the current gen already on its way out?

In 2012, Nintendo started out the current generation of consoles with the Wii U. After the much success of its predecessor, the original Wii, Nintendo tried to capitalize on that success with the tablet as its default controller to present a new way of playing. Unfortunately, that didn’t pan out so well, only selling at a measly 12.9 million units thus far, and on the pace of becoming the worst-selling console in the storied company’s history. With only the mention of the new Zelda game at E3 and the development of the code name NX, Nintendo seems like it’s calling it for the Wii U.
In 2013, Sony and Microsoft released the PS4 and Xbox One respectively with the former selling at 40.7 million units as of now vs. the latter at 21.7 million. The PS4’s power and affordability made the entire difference between the two and has not looked back since.
But now for E3, there are rumors of a new “upgraded” console for the two systems. Sony is reportedly releasing a new “PlayStation 4K” while Microsoft is reported to have a “beefier console” that is “four times more powerful” than the Xbox One out in 2017.
The question is: is the eighth generation on its way out in such a short period? It seems like it.
While the PS4 and Xbox One are significantly more powerful than its predecessors’, it wasn’t the great leap gamers were expecting like the last transition. It looked a bit more detailed, but it wasn’t the take-your-breath away like it was with the Watch_Dogs demo a few years ago (and look how it actually turned out). The Nintendo Wii U, in retrospect, was a seventh gen console in an eighth gen’s clothing; more and more people are rejecting Nintendo’s “gimmicks” in favor of a more traditional-style gaming in terms of better graphics and hardware with tried-and-true gameplay.
Last generation showed the games in 1080p, but this one is either the same or actually worse. The PS4 and Wii U still have 1080p whereas the Xbox One is in 900p. This is inexcusable, and perhaps the reason why the eight gen is about to die off so soon.
But the rise of 4K is perhaps the ultimate reason on why Sony and Microsoft have decided to change gears for the next gen consoles, even though only 15% of U.S. homes will have a 4K TV by the end of the year, according to Sony. Not much is known about the NX for now and perhaps for a while since it will not be displayed in this year’s E3.
It is rather a bit disheartening to those who have invested in their now-current gen consoles, only to have discovered that the new consoles could be coming out soon, thus making these ones obsolete. But one can only hope the supposed new consoles that will be out next year will give gamers 7 to 10 years to enjoy their consoles like the Wii, Xbox 360, and PS3.
