For now X.org is being fixed to implement support for many multi-card configurations, and as of Mint 15 many multi-GPU computers are working somehow. But I don't know how long it will take until the HDMI monitor with Optimus works too.
By the way, there are some computers with Optimus that have the HDMI port wired to the Intel GPU, so don't be surprised if some people are telling you that it already works for them.
