They'll either make their games exclusive to various consoles (PS for certain games, XB for others) so as to make the most use of the hardware that best suits their idea. It's their current philosophy and that wouldn't change.
And they would likely become the very best dev on mobile platforms, even opening up a new market on that platform.
They would make possibly even more money. But they're already making money now all things considered so this never was an issue.
