IIRC the Necron centipede is now 205 points (10 higher than the experimental rules), in the new IA Apocalypse rules, someone was complaining about that
As stellios says they had some lush gear on show, but very little new and from memory from what was said in the Seminar they intend to try and keep stuff quiet until a few weeks before launch (one of the reasons given for why White Dwarf has been getting sent out to subscribers later than it used to be).
re the selling stuff, we stopped by to look at the sales area several times and put it off due to the massive queues until about 10 to 3 when it was pretty much gone, so we were able to just walk in and get what we wanted from the FW stand.
From what one of the guys said when my brother commented that this was the first time in 5 years he'd been able to make it to the stall on the day, it sounds like their hands are tied to a degree by what the venue allows in regards to the layout.
I've got a bunch of pics to post on another forum later, so I'll copy some of them into here
(I've already put a few in the random thread).
What I didn't see was the golden demon models, as it seemed to be very crowded around them and I was too tired to try and get near those cases, I regret that a bit, but I suspect there will be plenty of pictures of them on other sites.
