I think we are looking as spells such as entangle to be a thing of the past.
I think you're wrong. Classes change, but there are limits.
I'm sure a wild shape focused druid will be an option.
But every implementation of druid has them as primary casters.
I expect them to be jack of all trade in a very similar way to 4E clerics.
4E clerics can melee attack, heal, buff, ranged attack and aoe damage.
I expect 4E druids to melee attack, heal, ranged attack, aoe damage and aoe control.
I do expect druids to be better at melee and worse at healing.
That's how the relationship between cleric and druid has always been.
Clerics are better healers and druids have had better offensive spells.
As evidence check saric's and malcolm_n's druid classes. They both have wildshape as a viable option, but in neither case is it the only option.
