From the promo pics, the Scarlet looks amazing. But to get that setup, it'd be amazingly expensive as well. I would think most pro photogs would get the $7,000 S35 for the Canon and Nikon lens mount options. A tad expensive but great value for the $ if it lives up to the hype.
Would love to have one, but it's way too much camera for me.
Oh, and for the Red lovers:
