Until we get the druid in our hands which should be this week(?), it would be hard to say.
But from what we were show, I think the druid is mostly in line with how it is in 5e. The druid is on the upper end of power potential in 5e. Being able to change into any beast with some limitations is really really powerful, and all the circles are really good. The extra health bar, the strong spell list, and the nature related stuff is very strong mechanically and has a lot of roleplay potential. Goodberry is nice to have.
In short, the Druid is supposed to be strong.
