i think MRK/SGP has to be at the top of the list. 184 would be a great fit with boceprevir (why wait for their own polymerase to reach the clinic and be that much further behind roche and gild)
i think gild and vrtx should take a hard look, but if they seem sold on the fact a non-nuc is enough of a complement to their protease then they might not be biting
another player that i think would be high on the list is actually BMY. their NS5A inhibitor is much like a protease - high potency and (presumably) low resistance. complementing that type of drug with a lower potency higher barrier to resistance drug makes sense. they also have a protease in the preclinical stage
certainly there are other potentials, but one company that surely doesn't need 184 is roche (unless their current nuc bombs on renal tox)
PS: fwiw i think NVS would NOT have made as good a fit as some of the others i mentioned PPS: a partnership may not be consummated until some 14 day data emerges
