I believe your point is valid. If the universe ends in big crunch there may also be insufficient proper time to form a singularity. People often confuse event horizons for singularities, partly because of Penrose's work. :) I think Penrose has made many contributions worthy of recognition, though I am not sure Nobel committee press releases are the best place to look for them.
