>since these SoCs are only barely more powerful than the 360/PS3
The benchmark from NVidia suggested that current gen Tegra can compete with Core2 Intel and XBox360 is slower AFAIK. Tegra.next (next gen ARM, ~2GHz) alike could just be the thing, because a) better hardware architecture allows more efficient algorithms (SM5/OpenCL) b) it would probably allow them to profit on the console instead of making a loss.

Games parallelize better than other software.
