From the tl;dr all the info on the TROPIC01 is it pin and / or instruction compatible with other secure elements to any degree?
For the wallets that are almost done now or will be done by the end of the year they are going to be using whatever you can get today.
I am not sure if it's going to be compatible with other secure elements, but it's going to be more secure and transparent, so that means no more hidden NDA's.
Current market is hungry for secure elements of any kind and I am sure they are going to have very good sales if they manage to pull this of in time, and use current global chip shortage.
Behind the scenes Trezor is 100% already working on new hardware wallet device that is going to be compatible with this secure element, that is the only way they can compete with ledger.
I will always choose open source hardware wallet with transparent secure element, instead of black box NDA closed source marketing propaganda devices.
