I'm going to guess at 30 € for the new edition - but availability at "cheap stores" will probably make it 19 € if you shop around. First 10 € sale by winter.
Apparently GW has removed Slann from the stars, and say that they are really old Lizardmen now. (I.e. fat gits)
They've also butchered the fluff of Grey Knights, Blood Angels and Necrons in 40k - so lets just ignore what is canon and go with what we all know to be true
To be fair, blood bowl essentially has nothing to do with GW now. The NAF do all the rules tweaking, so unless they remove them from the rules pack, they're a legitimate team in my eyes.
The only legitimate fluff for GW is written by Dan Abnett or Bill King, the rest of them suck.
As a point, Cyanide has just released a game based on Confrontation (a TT skirmish game produced by the now defunct Rackham). Apparently according to RPS, all the usual issues found with the BB netcode still remain, Poor AI etc, poor implementation of real time.
One of the posters over there made a fairly astute comment that since Rackham no longer exists, this would have been perhaps the only chance to implement a direct conversion of a tabletop wargame to the PC, complete with all rules, without the company having to worry about it impacting sales of miniatures, but cyanide had to go and fuck that up too.
