If the Tegra 2 rumours are true then this setup (3.0TF) would be:
230% XB1 (1.3TF)
166% PS4 (1.8TF)
75% PSPro (4TF)
50% Scorpio (6TF)
NS + NSlite + NSi + NSXL = 'Next-gen' console
If Nintendo stays at 1080p while the 4K Twins go higher res then Nintendo won't need most of the extra horsepower.
Two NS alone would be halfway between XB1 and PS4.
