This is 2.0 and Bada's been around a couple years already. For now, it's more low end than Android, but Samsung's reach is huge these days and I'm sure they privately see it as a nice contingency plan and bargaining chip to balance against Android, as the technologies and business relationships evolve.

I doubt Google will try to take things more vertical with Motorola, but it's one possible scenario where Samsung will be pleased to have a headstart should they need to put another OS on their leading devices.

Bada is more for lower end smart feature phones. As the lowest of the low end market gets more capability, you need an OS that's lighter than Android but better than the Java ME junk from 5 years ago. Thus, Bada. It's an OS for smarter dumb phones.

Samsung's also been developing Enlightenment (previous discussion: http://news.ycombinator.com/item?id=2495826 ).

No.
