I ordered both the M1710 and the M1210 when they were new, and in both cases the ship date was 1 month out initially, but the actual arrival date only ended up being around 2 weeks from the date they were announced.
I wouldn't get your hopes up too much, but I'll still be surprised if they really don't arrive until 7/29. I have my money on a week from Monday, but that's pure, unadulterated speculation.
