Such whining. "This is why I don't give my money and wait, this is why I wait then give my money."
If you think preorder shipping times are set in stone, and laws that not even God would dare break: wow. Either way, waiting on shipping if your funds are already allocated for the purchase isn't going to get in the way, especially for a hot item that's going to be shipped out first come first served. How much interest were you really going to collect given even a month delay?
Do you really think there's a chance in hell DJI is not going to honor your purchase? Has that been an issue yet?
If they didn't honor your purchase, do you believe your bank would not return the funds and pursue them for fraud? Who owns a visa/mastercard/etc w/o fraud protection these days? If you do, get a real bank.
I mean seriously, you guys are acting like its the end of the world. If you made a decision to sell your drone and buy a new one that hasn't even landed stateside, you lost that gamble. If you really needed it, then you wouldn't (or at least shouldn't) have made it. If you really didn't need it, then you're just being a brat upset because they can't play with their new toy as soon as they hoped.
I saw the delay, and am thinking oh well, I ordered through B&H who are not even going to bother shipping until the 28th because of Sukkot (something tells me Adorama is in the same boat here). Hell the stores won't even have them until a few days later.
You could try and remain hopeful, and believe that end of month/early november dates are still achievable despite the shipping delay. (Apple has been able to do this w/ fast international shipping from china right before expected release dates). You could accept it and think, well, november isnt that long, and there's a chance you might have to wait a little longer, or you can fan the flames of pointless fear and paranoia like those of whom haven't even purchased it but are still complaining.
Even if DJI did what they did to screw over GoPro's Karma, I'm glad they did, because I'd rather wait a little more for a clearly better and more portable drone. So honestly, I'm happy they released a sneak peak because I was tempted by the karma until DJI gave me a reason to wait for their event.
