Cafeen, I really doubt it. If that is the case, let's say a character has 41% item haste, 59% haste VoG, 60% bard warsong of zek, and 30% call of muse (call of muse is overhates, breaks haste cap) ~= 190% haste?? This is impossible to be true.
Both the buff icons from VoG and Warsong of Zek will be up, but that doesn't mean their haste are adding up. I often have up to 4 haste icons up on my buff/song box, but only the highest haste takes effect. If you want to try it, get a shaman haste, an enchanter haste, and a bard epic proc (55% haste), and bard haste song; you'll see all 4 icons up and running but I generatee you that only the highest hast takes effect.
Regarding haste cape, at level 60 character has a haste cap of 100%. And the 10 weapon delay limit has been removed.
