Noticed today that there is an X01 option and some component changes.

Was (and still am) planning for a Race build this fall and HAD been planning on an immediate wheel upgrade. I'm wondering if anyone is familiar with the DT Swiss XM LTD rims? I had read some complaints with the previously spec'd rims being not quite appropriate (XC) for the intended use of the bike and wondering if these are more appropriate? I can't find any info on the web.
