November should still be easy sony win, but december will be interesting. I always look at it from my own view, people ask me often which console to get.
I will recommend the PS4 Pro, if they want or have a 4k television, or want something most future-proof, but a lot of times people will say they find it "too expensive" and then I do recommend the Xbox one S, since it has backwards compatability, 4k upscaling and a UHD drive, and its quite a good media centre with the VLC app.
I've actually sold 2 people on a ps4 pro at work, and 2 on a xbox one S lol. But for me personally the PS4 slim is just not the slimmed down version I expected/wanted from sony. I am still rocking the ps4 launch console and I guess I could be happy im not missing out on anything, but if the PS4 Pro won't push sales over the xbox one S in december, im quite sure the slim version won't.
Anyway, interesting time and its good for gamers there is a competition going, as proven in the PC market its never good for prices and quality when one overtakes the other, with ridiculously prices Intel and Nvidia processors at times lol.
