Too bad nothing in this game treats attacks and ranged attacks separatly, we could have found interesting results about what is really considered a "ranged" attack.
It was a punch in 1.0 because Bard needed arrows for attacking, and they didn't want auto-attack to burn your ammunitions too quickly.

I suppose when the Musketeer-or-what's-its-name will come, we'll have another weapon weapon based on DEX.
But still, the only weapon tied to DEX is a bow, whereas all close range weapons depend on STR. And, looking at the trailer, you can't deny that Rogue has a really "close" ranged weapon.
