I think the last few gens and the start of this one has proved that none of the big three is that important. If one fails there'll be others (potentially) picking up the slack. It's very possible that the industry will shrink because of it but it won't die.
Edit:
I do however believe that Sony and MS are easier to replace simply because of how similar they are to each other.
