Well I'm sceptical about Samsung themselves running a wallet. You have nodes, maintenance, keeping on top of forks, upgrades. If I were them I'd much rather leave the actual operation to other parties who are interested in doing it.
Look at the amount of hassle Ledger and Trezor get from their users regarding firmware, forks and adding projects. I can't see Samsung bothering to engage with users like that, and users won't put up with faceless masters.
Much better for them to plop a storage solution down and let the rest of the world make something of it. It sounds like they're rolling out soon so we'll get the juicy gossip rapidly.

It looks rather wallet esque after all. And they have a weird ETH fixation.
