Let's hope this means ImageWorks is completely out.I was browsing around trying to get info on the main special effects house hired for Man Of Steel and it looks to be good news!
It looks to be Double Negative per IMDB.

I was hoping for Digital Domain myself, but Double Negative has a fairly extensive body of work that is suitable for this scale. My only (small) gripe is I always find even their best stuff to be slightly noticeable as CGI, whilst still being technically impressive. ILM and WETA have very often crossed the border of awe-inspiring and unbelievable visual effects. But that's pinching pennies at this point. I wanted a capable studio, and it seems we have one.
