Please take this with a grain of salt, but I ordered a hybrid 5 a couple of years ago and the backordered date was something similar with it being several months out and it ended up arriving significantly ahead of that date.

Like you, we are Titleist loyalists and not employees of Titleist. With the supply channels on a slow boat from overseas, it is most likely. Those dates your retailer gave you are pretty accurate. If they come in earlier, it is a bonus. Have been waiting about six weeks for a new driver, but due to the shortage of Fujikura shafts, it has been delayed, but on the bright side, it is on the FedEx truck and will be here tomorrow.
