No but I believe you are wrong on this subject.
Quoted from a blue.
"Rated Battlegrounds are broken down into three brackets. 10v10, 15v15 and 25v25. These brackets rotate weekly and can be viewed in-game via the calendar by activating the battleground holiday filter."
Seeing as they are broken down in brackets I feel they will share the same liberties as arena did, so they will rotate maps or in this case battlegrounds. So if the week is 10v10 week, we may participate in either Warsong and the new 10v10 map coming out. 15v15 will include SOTA/AB/EOTS, maybe a new one. And then 25v25, will include IoC and AV.
