Hey folks,
I have read through much of the rumor mill but I have to admit, I still don't get it.

Is the Nagash End of Times book a new rule book? Does it replace the old one? Do I need to get it to play games at my local hobby store?

If you can lead me out of the dark I would appreciate it.

Also- has anything been said about ogres going forward? It is my only fantasy army and I havent heard anything about them-

Thanks for your time.
