I talked to Ducati Seattle today and found out yellow will be available in the standard model (I still opted for red).
Here is the information they posted to another forum:
1098 Base: Red w/Red Frame....Yellow w/Black Frame
1098S: Red w/Red Frame....Black w/Red Frame
Tre Colore: Red/White/Green w/ Gold Frame
