Market researcher says Cristiano Ronaldo on the cover of FIFA 18 could boost sales 10%

“Depending on the popularity of a player, a famous athlete can help improve sales by about 10 percent. Suffice to say that signing an athlete is critical, especially because the audience for sports games tends to be more-or-less stable.” - Joost van Dreunen, CEO of market researcher SuperData

I guess we won't really know how having Ronaldo on the cover of the Switch version will boost sales, as there's nothing to compare it to. Ronaldo has a lot of work to do on the Switch version, as fans have been left pretty upset by today's news.
