Going from 1.24 to something like 3GHz is completely out of question. Wii U's CPU is built around short pipelines, which means low clock speed but multiple instructions per cycle. Some people were suprised Nintendo got that 1.24 GHz out of the PPC 750.
Still, a smaller bump to something like 1.49 GHz (would be a clean multiplier) seems definately possible.
