Brickset has posted pictures of a new Summer 2013 Superman set. Superman: Battle of Smallville. No word on price or piece count but you can see for yourself that it'll be a great set. The minifigures are especially good. Though the weapons used by the bad guys look more like a sextant than a weapon to me.
Price will probably be in the $40-$50 range. With piece count probably 400-500 pieces.
Overall an exciting set. Can't wait to find out more!
