Is it too much to ask more of them? If their dates mean nothing, then what does that say about them? If a store claims to be open at certain times of certain days, yet is often closed when I show up to shop on those times and days, it doesn't take long before I start shopping elsewhere, as long as I can purchase the product I want, or a suitable substitute, elsewhere. Your advice to not pay attention to internet rumors is sage advice, but what some of us are less than pleased with are comms right from "Nikon's mouth"....
Anyone who is heavily invested in Nikon just has to learn how to interpret their marketing/advertising. It's simple. The technical information is accurate. The dates mean nothing. It'll be here when it's here :( And heaven forbid don't pay any attention to the blogosphere predictions.
For those like me, who are very invested in Nikon, and/or just feel like I'm too old to change systems, the current time is a crossroad. It almost is changing systems by going to Nikon Z cameras and lenses, and if not for the FTZ, it would be. Looking ahead, instead of both ways, might lead someone like me to go ahead and seriously look into changing from Nikon to Sony or Canon (or another) for mirrorless offerings. I don't plan on purchasing many more photography items in my lifetime, but those few will be a substantial expense. I'll wager that Nikon's workforce and shareholders would like me to spend my money on their products, and not on their competetors'.
