Their geared fan is interesting; to my mind it would allow them to design for optimum LP and HP shaft speeds (just like RR can for their IP and HP shafts), and choose the ideal fan speed by picking a gear ratio (just like RR do with their LP shaft).
But it will be many years, if ever, before we see a GTF on a wide-body/long-haul aircraft.

Which reminds me, weather permitting, tomorrow should see the first flight of the CSeries.
