This morning, the refurbished 70-300L showed up as in stock again and my order was still "on backorder". I called Canon and they confirmed two (!) lenses in stock. The Canon rep also confirmed that for no obvious reason my order was held. After he resubmitted the order, the status immediately changed to "shipment pending" and now is on "warehoused".
So, at least with my order there was a problem and maybe others are experiencing the same thing.
Btw, it seems to be selling quite well. The second lense has been sold already...
