You don't think that the Valley will be crossed for video games in the next ten years?
Considering how rapidly the digital technologies make it from big screen to small, I'm guessing that we can see the Uncanny Valley crossed (for Video Games) within 2 years of its closure in films (the vast majority of digital films having crossed it).
Part of the reason is that the software packages that do things like Digital Emily (mentioned below) are so easy to buy now. They no longer cost hundreds of thousands, as they did in the early days of CGI, and even huge packages like AutoDesk, which used to sell for $25,000, now can be had for only $5,000. And, those packages can be had for a similar price. That is peanuts when compared to the cost of the people who run that software.
I agree with you. The uncanny valley refers to rendering human actors only. It is not necessary to render a whole movie from scratch. It is much more work, but only work.
IMO, The Life of Benjamin Button was the first movie that managed to cross the valley.
I would like to propose this as a thread for people to write in their predictions for the next year and the next decade, when practical with probabilities attached. I'll probably make some in the comments.
