They got all 12 correctly despite them usually getting some wrong!

Yes!
I read your post this afternoon and told a work colleague who I thought was going in, they will be most impressed with me on Monday as they were all 100% correct.

just goes to show how sh!te Channel 5 are at keeping things under wraps. I was hoping for at least one or two surprises

Yes they got them right a couple of hours before the launch when everyone pretty much knew about all but two of the housemates anyway. Doesn't really make up for all of the "CONFIRMED" housemates they were spouting on about the rest of the week who turned out to be completely wrong as usual.
