" support for pairing multiple Passport prime"

I could ask what the point is. I really doubt that anyone will own several Passport Prime devices, each costing around $300.
When I saw this in cygan's post, it immediately reminded me of Ledger and I think the Ledger Stax. They advertised them as devices you could stack one on top of the other and display your NFT collection, one unique NFT per Stax.

I am thinking Passport Devices thought of a better use case than that...
But I’d strongly advise you not to rush into moving your funds to Passport Prime, especially if you already have Passport Core.
Passport Prime runs on KeyOS, which they built from scratch, and who knows what “surprises” this OS may reveal over time.
I wouldn't move the coins at all. Both devices are airgapped and from the same manufacturer. He can just recover his wallet from seed instead of creating a brand-new one and starting from scratch.
- If I didn't trust Passport Core or think it was good enough, I wouldn't buy it or use it until the Prime arrives.
- If I didn't trust that the company did a good job with Core, I wouldn't buy Prime from them.
