That also implies that there is more to get excited about. It’s entirely possible that the leaks have completely stolen the thunder of their big reveal.
I also suspect that when they say “not official”, what they really mean is “not final”. i.e. These are prototypes, and could change by the time it’s officially announced. They could also be contractually limited from statements, in a “we can neither confirm nor deny” kind of way.
I do agree with your larger point that their press release left something to be desired.
While technically true, this really doesn’t change the question. Life is a complex series of chemical reactions; death is what happens when these reactions stop.
Let’s say you die of heart failure. Your heart stops pumping blood. Then the brain stops getting oxygen, due to the lack of blood. Then rigor mortis, and so on. If these aren’t all fixed, you would also re-die immediately (actually, without the brain function being fixed, you would never really be alive again).
The premise assumes that all of that has been addressed by them coming back to life. Adding a few external factors doesn’t change that. If it did, the simple fact that most people are buried and would suffocate would render the point moot. Same for decomposition.
Although cremation would be awfully hard to tackle…
