So the reasoning is: video games are popular, more guys than girls like video games, some recent crappy chick flicks have done well, therefore we must no longer market to men and focus our attention on making shit for women.
What half-assed analyst came up with this conclusion? I thought dwindling sales in a demographic meant you had to shift gears to bring them back, not ignore them. And besides, there will always be filmmakers looking to make adrenaline-filled, cg-heavy summer blockbusters and execs will say okay because those make money hand over fist. All this means is that studios might (might!) greenlight an extra chick flick or two per year. Whatever, I ignore 'em anyway.
Also, "women" refers to a lot of people, not all of which enjoy crappy date movies. Both genders enjoy good dramas, thrillers, and action flicks. Way to over-generalize, movie execs.
