Safe to assume the 135 Art won't follow the trend of other Art lenses and have a 1.4 aperture. That would be a monster. Maybe f/1.8 but if it is to compete with the current 135L then certainly no slower than f/2. Can probably also assume it won't have IS in the Art version. The 135L is old technology but by all accounts a stellar lense and not overly expensive as L lenses go. So the Sigma will have to be darn good optically and below the price of the Canon you would think.
