So The NX isn't coming out 2015, they said there would be more information about the console next year, 2016. So probably not even the new console 2016, but 2017, which would mean 5 years, which isn't that bad. So 4 years after the PS4 and Xbone were launched, and the PS4 and Xbone were outdated at launch. I think it needs to be a solid upgrade to the PS4 and xbone.The PS4 and Xbone probably are going to last to 2018-2020? I don't see them lasting past 2020.
The desktop market is shrinking. In the future, it seems like it will be only needed for gaming or professional use. The new Macbook has a tablet cpu, because efficiency is more important than raw performance with mobile devices and ARM is the king of efficiency and AMD is releasing an ARM desktop cpu in 2016.
I don't see the appeal of x86 for a console released in 2017, unless intel pays them a shit ton. Why would they adopt a dieing architecture that is less efficient if there is comparably powerful gaming cpu's using the same architecture used in almost every mobile device?
