The Citigroup analyst is out to lunch. 1) if those 99% cure rates hold with SVR12s then it is a better drug period than Harvoni whether 8 week or 12 week. 2) ABBV is going to test it in 8 week so there is still a solid chance they have a competitive 8 week as well.
Another brilliant commentary comes from Leerink who has MRK getting approved in 2015 now even though it's already April 9 and they don't have BTD for all of GT1.
