PCs are supposed to always use at will powers instead of basic attacks, and while there will possibly be feats to allow the powers to be used with a different weapon than the default one I don't think there will be a way to make a melee only power useable with a ranged weapon. Also its very likely that only the most basic powers are melee or ranged as those have to be fairly generic.
All this means that what powers a class has determines if that class can use ranged weapons effectively. Now lets look at the classes.
The ranger is obviously an archer guy, no question there.
Wizards and Warlocks have spells and no need for a ranged weapon.
Fighters an Paladins as defenders are supposed to be in close combat with the enemy so they likely won't have many ranged powers
Rogues have some ranged powers (see article) but they are, at least how I understand it, supposed to be light armored melee fighters so the majority of their powers will probably be melee only.
That leaves the Cleric and the Warlord. I don't have much information about them but I think the cleric will more be a spell guy while the warlord looks rather melee orientated to me.
If that is correct then the Ranger would be the only one who really could use a ranged weapon which imo would be rather sad. I hope I am wrong and that all classes (except maybe the spellcasters) can choose some ranged powers without needing to multiclass into ranger.
