I have to agree that the idea of having the Kinnect with every single Xbox One console was a bad idea from the outset, and the extra $100 on the price was no good either. It has looked for a while now that the PS4 would massively out sell the Xbox One, but if Microsoft does pull themselves together and get rid of all of the rubbish they tried to enforce, they may stand a chance of competing. As a Sony fanboy, I am still quite pleased to see that this time around the PlayStation console has the upper hand, however I worry that they may become a bit complacent and Xbox may just win the console war.
Additionally, it might be worth mentioning that the PS4 had originally come with a playstation eye too, but they removed this at the last minute as a way to compete in regards to prices. In my opinion this was a good move but also a bad move by Sony, as it means that they now have ore people who are looking to purchase their console, however publishers may shy way from integrating the eye with their games.
