There's actually incontrovertible evidence that the images posted on this thread do NOT pre-date the raid.
The photo with a human being in it is from the set of "Zero Dark Thirty", which is easily Google-able and by definition cannot pre-date the raid.
The artists' impressions from David Cenciotti's weblog (
http://theaviationist.com/) are stated at the source to have been based on the wreckage pictured at Abbotabad, so also don't pre-date the raid.
If there are any other images of a stealth Blackhawk that purport to be a real aircraft (there are some videogame constructs) and which pre-date the raid, I'd love to see them but I don't think they were around.
