It may be that the GamePad allows them to include some interesting new features exclusive to the platform, but that also means more development time, which means a smaller profit margin, particularly since it'll be delayed. If they simply put the time into making it a stable, solid game on that platform, I'd say the odds are better than even that they could at least break even, though a worthwhile profit margin likely isn't in the cards.
Realistically, they're probably better off cancelling it. Aside from maintaining a toe-hold in the Wii U's market, I don't imagine it doing much for them.
I believe in honesty, civility, generosity, practicality, and impartiality.
