From the most recent Q&A. Fury won't be using Slam anymore, according to Ghostcrawler.
There is a new attack called Wild Strike. At the moment it is an off-hand attack without Slam's cast time. The Bloodsurge proc then lets you do 3 cheap Wild Strikes on a 1 sec GCD. Wild Strike also has the MS debuff, replacing Furious Attacks.
Also, warrior specs are going to get rotational abilities that grant rage, rather than costing it.
It'll be interesting to see how this will affect the stability of fury's rotation, as we currently can get somewhat screwed by strings of misses. I also like how Wild Strike can be used three times, which will help reduce the number of empty GCDs.
