...but not from FBTB.net, yet. Site The Pop Culture Network has several pages of LEGO shots from the American International Toy Fair. There's a lot to see, and I will be the first to admit I haven't gone through them all.
I have yet to see any pics of Series 6 of the Collectible Minifigures, so I assume that when the PR announcement from TLG referred to '48 never before seen collectible figures' they were speaking to Series 3, 4, and 5.
I'm certain the FBTB.net will post later today with additional details. Until then you can peruse the pages of The Pop Culture Network.
Thanks to various e-mails and A Modular Life for pointing us in the right direction.
