I think a more interesting question is what will Paizo do to protect their niche when 5e comes? Will they lose customers to the new shiny? What are they going to do to fight against that?
At this point, I don't think Paizo has to worry about it.
Their core book is on something like a 4th printing.
Their starter boxed set seems to be doing well.
They have numerous support books already printed and more in the pipeline.
Their adventure path program shows no sign of slowing down.
They are expanding into comics, miniatures and online gaming.
To 'fight' the shinny, I suspect they'll have stuff like the omnibus edition of Rise of the Runelords, along with the new miniatures to go with it, along with new books, adventures, and various other bits.
Not to mention anything 3rd parties do with the OGL in full support of Pathfinder.
