There was talk of the T900 for the A380 being RR's first contra-rotating engine as an improved bearing design had been produced
The Trent 900 will not have conter-rotating spools, but the Trent 1000 will, so will GE's B7E7 engine. GE's Unducted Prop Fan (UDF) had counter-rotating LP spools. The PW6000 will have counter-rotating HP-LP spools. In fact, because it has counter-rotating spools, the fan rotates in a direction opposite to all the other P&W commercial fans, that is, clockwise foward-looking-aft.
