Actually it won't be like BorN because it adapted 3 Volumes, while season's 1 & 2 adapted 2 volumes each and they turn out OK.

So if they continue making more season's, each one will have animated 2 volume's, although by Season 9 they'll probably need to have Volumes 19, 20 and 21 together.

Not sure if they'll adapt EX into anime but it be great to see.
