@jgeewax We never use Entity.reload() within the library and it doesn't seem to be particularly useful and can even be replaced in a one liner:

entity.update(entity.key.get())

What did you have in mind when you implemented it?

To give some more context, we have been discussing / making a case for removing Entity and just using a dict (as in gcloud-node) since most of the logic lives elsewhere. Entity.save() can be moved to gcloud.datastore.__init__ and so reload() is the only remaining blocker.
