Space Hulk

So the mystery box was announced, and as everyone had been predicting, its Space hulk!
I'm in two minds about this release. The new models look nice, but the price is quite high (£60!). Can anyone confirm if the rules have changed or are they exactly the same old rules? Not sure i can be bothered to buy if its just the same old rules (£60 for some terminators and a couple of genestealers???!).
If they are new rules then its a totally different case and i need to get my order in!

Is anyone else getting excited about this? I've not seen a massive buzz about it amongst the bloggers, which is odd, especially given the "limited" nature of it. Also, is there only me that thinks its a little odd to do a release of a big box like this in limited numbers?
