The cd on KS and brews decreases, the point haste looses defensive benfit is where you can't utilise all the brew charges which I'm not sure is realistic at any achievable haste rating. With the one caveat where there is still an internal CD on using brews, you just can't spam them, I think it's around 1s, though I haven't double checked it. Even with all the anecdotal accounts saying they have all the brews they can use I'm pretty sure PB is under utilised.
As to offensive benefit, probably when you can actually spam KS on gcd, which is again not achievable.
That is not to say that other stats are worse or better, truthfully modeling ISB / PB usage is a nightmare since the APL in simcraft will have to take your haste level into account.
Simming dps though should be easier to at least find out if haste is better dps wise than other stats.
Edit: Actually if we compare the value of 33% haste vs. crit with a baseline of 0 for either (which is obviously wrong) we get that at least in terms of damage KS does, they are the same, eg. 1.33ks vs .66ks + .66ks (1ks * .66 regular hits + 1ks * 2 * .33 for crits). And since haste doesn't effect BoK or BoF it would seem crit would be better dps wise, I didn't take into account their relative rating though, I'm not sure but I think haste is generally cheaper.
