We'll have to wait and see if Fantom X has better sounds than Motif ES. I think currently Motif ES beats any Roland or Korg offering hands down in sounds department.

I too have my eyes on Fantom X, and sounds will be the deciding factor for me. I love Yamaha drums and acoustic sounds. Another setback for Roland is that it can't read any of the popular sample formats (Like Akai for example ...) I hope Fantom X can read other formats otherwise that 1GB RAM may not be as usable.
