Well here's the quote
"So in Texas, we’re building the Model Ys with the structural battery pack and the 4680 cells, and we’ll start delivering after final certification of the vehicle, which should be fairly soon," So You can read that in one of two ways. The Model Ys in Austin will be 4680 or that they are building some with 4680s. Again, technically it could be both but you would probably not word something like that if you meant you're building both. Possible, but awkward.
So yes, you could be right...but you'd have to be awfully jaded to think like that..which is basically everything they say is technically true but they're actually just lying to us...
