Agreed ... I also think this is an old picture only published now.
But these here seem to be new (at least the date says 9.9.10) ... and since they include a yellow J-10B, it seems to be a new (no. 4th flying ??!!) prototype.

Thnx for sharing! Those "fan qiang dang" are invincible!!!
Is it me or does the nose of the new prototype look crooked (curving downwards)? Is this the result of the photo-angle?
