What if he is correct???
We won't know until the dealer show if the information is correct or not. And without citation or source there's nothing now to assume that it either might or might not be.
This means that as merely an undocumented suggestion it helps absolutely no one up until the moment information is confirmed at the dealer show (i.e., exactly the same as without the uncited post). No one in their right mind would alter or make a buying decision based on unsourced data and there's nothing there to definitively end any other speculation. As it is it's only a list of nomenclatures that someone quickly typed out.
In other words people are in exactly the same position with or without the unsourced data. That's why, even if it later turns out to be accurate, it's not worth a damn thing
now and is still just more playground rumor.
