Probably more dependent on where TSMC are with their 12nm node. If yields are good it'll be cheaper to manufacture, or if they've more capacity on the 12nm vs 16nm, then why not move now. A smaller node should yield bigger profits sooner.
Also there's the memory shortage issue, if it can use more variants, there will be more availabilty. I assume Ampere will use GDDR5 on the mid range, GDDR6 on the top end. Just a guess though.
