Depends on when it's released. The Tegra X1 is delivering 1 teraflop next month in tablet format which is pretty significant. Who knows what will be possible in another 18-24 months.
It also depends on whether Nintendo insists on following the small form factor, low power consumption of the Wiis. Considering how small the Japanese market is these days I just don't think it's a goal worth pursuing.
