Interestingly, there are a few people who are enthusiastic about the new version. I have been talking with a few on Twitter. Largely, it seems that there was a group of people who were on the edge of WHFB, and were already 40K players I think, and who are now looking at the simpler rules and more relaxed attitude of the game and looking to graba few kits, since they can now buy anything that they want without having to worry if it is 'rules legal'.
This is certainly not for me, although I was never a WHFB player either, and I think that it will lose more players than it gains, but it seems that there is a target audience out there, however small or temporary they are. (And, these are people talking about getting into it.... Time will tell if they actually do.)
