All of my sites lost a point in PR .. every one of them, one point accross the board, so I can definately say, sites with PR got updated hehe
How on earth can I have a PR4 homepage, and have PR6 interior pages? I think Google needs to address this issue because link partners are giving me a hard time since they are being exposed to an inaccurate number.
Looks like you’ve got some great stuff goin on on some of those inner pages 
Congrats! PR4 btw, seems to be about the avg for gambling (In my non scientific surfing obsering opinion only) PR6 is awesome
