in all reality, this new feature probably was done outside of PD, but using some SONY web service group...
the game is not really changing to make this work.
now, I do like the idea of the photostream but it would be better if we could store hundreds if not thousands of files and each have our own gallery to display things...
it sux that we'll be limited to around 5 photos and hopefully photographers with more "cred" so to speak, will be favored over people just posting funny stunts they've done with cars.
hopefully it's quality more than anything else that determines what is shown on the photostream.
