I have always been a pc gamer first (well, after the snes era anyway) , but have always owned at least one console for the exclusives and what not. Lately though, more and more games tend to go multiplatform, and I started thinking about the PC more as a mainstream gaming platform and alternative, instead of addition to a console.
With the new consoles, I was kind of curious to see what kind of features they would incorporate. Perhaps there would still be something cool and unique about them that would lead me to get a console next generation as well. But after the Xbox one presentation, I was not that impressed. It seems that the key features they are adding are more generally TV and media focused, rather than gaming focused. This is why I think I will just stick with only a PC next console generation. The reason I opt for the PC over console is because almost all the games I mainly play are PC exclusives (Starcraft 2, DOTA2) and for my favorite genre, FPS, I have strong preference for the default input devices on the PC.
Long story short. The new consoles do not add any unique features that appeal to me. And since multi-platform seems to be the standard for games nowadays (perhaps even more so in the future) , and I care more about PC than console exclusives, I will just stick to PC.
