For one I think NX isn't a single device, instead it will be a family of devices available in different form factors and have different specs. Perhaps something like this.......
NX Portable-300 gflop, 2gb RAM, plays games at 540p
NX Console-1.2 tflop, 8gb RAM, plays same games at 1080p
NX Tablet-somewhere between Portable & Console, plays games at 720p
I also think we may no longer have generations in the traditional sense of supporting a device for 5-7 years then moving on to a completely new device. Instead I think we could see these devices being upgraded every few years.
Perhaps 3 years or so after the initial NX devices release, they receive upgrades with basically 2x the specs, NX Portable is now on par with Tablet, NX Tablet is now on par with Console, NX Console is now 2.4 tflop with 16gb RAM.
All or 99% of games are still playable on the older devices but they will just perform better on the newer ones. Maybe once the 3rd generation on NX devices releases, the 1st gen will start to become obsolete but by that point they would have a full 6 years of support so it's still a full generation.
When the herd loses its way, the shepard must kill the bull that leads them astray.
