A few days pass, and they release a second post stating that they feel a full recall is in order (Feb 4th): https://blog.bambulab.com/a1-heatbed-cable-callback/. At this stage Bambu themselves don't have models in hand showing the issue, but think a recall is still in order.
They're offering either a replacement heatbed to resolve the issue (with very detailed instructions on how to install) along with some credit, or else a full refund also with some additional credit.
