Samsung has sent out invites to a Tizen event at MWC where they will present new Tizen devices. The event will be held at Arts Hotel in Barcelona on February 23, and it's invite-only. There is no info on what kind of devices they will present, but holding a whole event for just the announced Tizen camera seems like a bad idea, so there will probably be something more.
First Samsung announced that they will present Tizen phones at MWC, but later they took all that back and said no Tizen phones, so it is a bit of a mystery what Samsung will present on this event. And as I've said before, Samsung is moving away from Android, both by changing it so much that you can't recognize Android anymore, and both by going the Tizen way.
