I ordered one with mine in the first round and was told before it even got to the dealer that the 6' roof rack was so far backordered that they didn't have a delivery date. Didn't get charged for it when I picked my IG up and will have the option when it shows up (but still no timetable). If you really want one and you can't spec it with one I'm sure they'll be a few around when deliveries eventually start (who knows when?). Otherwise, good options are starting to show up (albiet shipped from the EU ($$)). Hopefully, an American company will try something out as well.
