Same, I can't wait until they put a ToF, but as someone else pointed out, if this is true and Apple has overcome the issues, they can introduce this feature as a software update when they announce the new AirPods.
I’m afraid that wont happen. The only reason I can think of for them pulling this thing last minute is some issues with overheating/burning... Apple just goes through a ban of all their MacBooks at certain airlines, I’m pretty sure they dont want to go through another one of these fiascos. So they probably decided to just pull all of the keynote slides and replace them with some awkward filler material (most likely the nervous Indian dude talking about the Bionic chip).
Now assuming that thing is fixable through firmware, why would Apple fix it. The damage is already done, whoever wants to buy the IPhone will do it anyways. Why not just call it a day and reserve the feature for the next models, giving buyers another compelling argument to upgrade.
I cant think of a single time in Apples history, were they would announce retroactively “Oh by the way, from now on our product has one more thing”.
But yeah, who knows, here’s hoping...
