In a recent photo preview article at Elite Bastards (link) we can see that Asus is adapting Lucid's mixed GPU technology as second manufacturer after MSI. The Crosshair IV Extreme, the bigger brother of the 890FX-based Crosshair IV Formula, hasn't been released yet and a specific date wasn't mentioned in the article. It will be interesting to see in what way MSI's and Asus' Hydra solution deliver the same or different performance.
