The new Belfast North West constituency is set to be the most intriguing one.
It could see one of the closest election scraps in decades.
Some of the typical unionist wards in the north of the area will be lost, potentially putting Nigel Dodds' seat up for contention.
Elsewhere, Belfast South West would run from the Lagan and include all of Dunmurry.
It will take in wards such as Colin Glen, Ballymurphy and the Falls meaning it's likely to favour a nationalist candidate.
However Sinn Fein's Alex Maskey says it's overall not a good move.
Meanwhile, West Down is proposed to replace the old Lagan Valley, taking in Newtownbreda, Knockbracken, Beechill and Carryduff West while losing areas such as Maghaberry, Lambeg and Hilden.
