News Intel Confirms NUC 12 Extreme uses Socketed Alder Lake-S Processors

If Intel historically doesn't support the same socket for more than two generations, then why? So we can upgrade to a 13rd gen i9 and that's it? And especially since you can get it with either an i7 or i9, it's not like you buy a budget CPU then upgrade to something stronger. Unless they support the socket for longer (yes, like AM4 is), then this may just add unneeded costs.
