They did on the Embraer 190 we flew from BOS to JAX except for Row 1 only which were fixed (they are fixed on the A-320's too). The row in front of the exit row (row 11) does not recline - they tell you this when you book those seats) The only other differences were only one row of exit seats, two abreast seating, and seats that are about a half inch wider on the E-190 versus two rows of exit seats, slightly narrower seats and three abreast seating on the Airbus A-320's.
