This is nothing surprising nor shocking coming from Nvidia. They have stated repeatedly that they don't see miners as a key consumer for their cards. They believe miners will come and go and market demand will spin on a dime with miners whereas gamers are near constant and growing over time. From Nvidia's perspective, it's better to serve a steady audience well than to commit substantial resources to a customer base that could dry up in an instance with the collapse of mining profitability.
Not that I agree with Nvidia's position -- just that as a share holder, I also get their business reports and position statements, so it's something I've seen them elaborate about multiple times over the last year.
