If the original one doesn't I'm going to be seriously annoyed. I bought one just for XEM. It's still sitting there unopened.
So did I.
AFAIK old devices are supported with a firmware update. But haven't tested it yet. Not even sure if the update is released yet.
Same here, my Trezor is still unopened. I don't think they've released a firmware update yet. Pretty sure old devices will also be supported since the guy who developed the code (Saleem) did all tests in an old Trezor.
