My estimate is 30-40% for all geographies combined. I'm counting on small but non-trivial 2014 Sovaldi sales in the EU insofar as EU countries will not want to delay the Sovaldi launch unduly.
If 100% of 2014 Sovaldi sales were in the US, my 30-40% estimate would be higher, so perhaps we're not that far apart.
