Cata prepatch BG bracket split

Hello, I didnt find proper place to leave my question, so I just gonna ask it in here.

This may seems obvious to somebody, but my question follows:

Will Battleground brackets be split 70-74 75-79 80-84 85 on prepatch or this will be changed?

I didnt find any info about that in recent posts, and people are talking different stuff, some ppl say they will leave it as it was in wotlk 70-79 for example, only thing I know it was not like this back in the 2010 release.

Thanks

As of now i personally have not come accross any info of them changing it to the ones we had up until now. The smaller brackets were indeed better balanced than the ones we had up until now and would be a shame to not utilize them.

No answers, nothing. Wow this is dead community.

Wasnt that done in mop?

After a little bit of research I found this :
