FWIW I thought Samsung trademarked the name MBCFET. Not saying that is in fact worth much, just that I know for a fact Samsung has been concrete about when this is going to be a process customers can use. On paper I don't think it's risky to say everyone is looking at GAAFETs and MBCFETs, they're the evolution of finFETs (okay, we have the fin, what about more than one fin? Okay, how about the channel is surrounded by the gate (Gate-All-Around)?) How far along is everyone to making them commercially available with good yields, ¯\_(ツ)_/¯. I think the surprising thing to me was TSMC has thus far (as of like a month ago) been of the mind "nah, finFETs are fine". But keep in mind, that was for their 3nm node, which this isn't. https://www.anandtech.com/show/16041/where-are-my-gaafets-tsmc-to-stay-with-finfet-for-3nm https://www.anandtech.com/show/16041/where-are-my-gaafets-ts...

That is certainly not true. TSMC has always had a conservative culture. They dont aim at x% of improvement per process node like Intel. GAA for 3nm has long been known to be not ready for 2022. They actually mentioned this in 2019. But it was only confirmed later at a conference that Anandtech picked it up. Mainstream media being an echo chamber decide to copy each other and the news spread like wild fire. So it was only logical to push those improvements to 2nm.

  You would have to be more specific about what you are claiming is untrue, that's a bit vague. I'm aware of how TSMC felt about the prospects of GAA at 3nm, and their view of Samsung's yield prospects (i.e. not great). Sure, it's logical to push GAA to the next node if you can, but part of TSMCs style is that they didn't even confirm that they were moving past fins until earlier this year.
