The other druid picture features a druid with an animal companion as well.
The druid (and the sorcerer and ranger) are sorely lacking in class options, but the druid seems particularly shallow due to the lack of a major class feature - especially in light of the ranger getting a class option with said feature. The optimist in me feels like they just cut back to make room for other content, and maybe the classes that were cut short just didn't have additional class options that were unique or balanced enough. The realist in me feels like they are just leaving a hole open intentionally for sales of later expansion books. (I mean: class options are an obvious way that 5.0 is going to expand in the future, so maybe the first PHB2 or "complete X" will specifically feature druids, rangers, and sorcerers?)
