New 248 (8% Hit Rating) in affect now?

I keep getting mixed messages on this subject; Some say it is affective now and some say not until Cat's release.

I don't want to re-gem and drop my hit rate to 248 in order to gain some agi or haste unless/until it is in affect.

Anyone know for sure on this?

Thanks!
Yes, it is my understanding the new hit rating is in effect.

However, technically, the actual hit cap is 246.xx (don't know the exact number). So shoot for 247 hit rating.

You can also look at the new character frame and mouse over your hit rating to see where your hit % stand against 80, 81, 82, and 83 level mobs. If they are all 0% then you are over hit cap (it doesn't tell you how far over hit cap you are). If it's greater than 0% then thats the chance that you will miss that particular level mob meaning you are under hit cap.
Thanks!
246 is 7.9999% or something like that. You still have a chance to miss but you also have the same chance at winning the lottery.
With 246, Imp Srpt Sting misses 2.5-3.2% of the time on HLK fight. No other shot misses.

(edit-- in my case, as per logs over the last 3 weeks.)
Ah. so the 246 has no bearing on it, for now?

Then, at 246 hit rating, no shot has missed on HLK--in my case, as per logs over 3 weeks. =D
Don't be afraid of having a little extra hit laying around. If you're like me, something like 250 hit is fine. You may belittle over, but there's no point in reforging down to that perfect 246 sometimes.
