Update: It looks like the TF700 isn't the only device new to the CM10.1 world; nightly builds are also available for the Nexus 7 (grouper) and GSM variant of the Galaxy Nexus (maguro).

The CyanogenMod team has been steadily working on getting Android 4.2 ready for nightly status, with builds already available for the Nexus 4 and Nexus 10. The newest member of the CM 10.1 family is ASUS' flagship 10" tablet: the Transformer Pad Infinity (TF700).
