[quote name='outsider']This *does* have a new dpad. Bought it last week from Buy because of the pad. I cant confirm its the same as the green one in EU, but I would assume so.[/quote]
This hasn't been reported anywhere, so I don't know. A lot of places ran the story about the green controller and how it would only be available outside of the US, so one would think they would also report that the improved d-pad would now be available via this package.
Anyway, as others have said, if you want to use wireless controllers on the PC, you need the adapter. The cable from the kit is only for power. And yes, you can use it without batteries.
