Yes, there will be. Even if the PS3 is a flop (which it isn't yet, whatever you might think).
One failure has never driven an established hardware company out of the running, and it certainly isn't going to happen with Sony, with the wild success of the PS2 still fresh in their minds. The brand still has value, greatly diminished though it is now.
Whether the PS4 will be the absolute trainwreck of design and marketing the PS3 was is another question.
