I saw one of them answer this same question like a month or 2 back. Since this is an XBLA game the max Gamerscore is 400. If they would want to add any more Gamerscore it would have to be added in alongside DLC. Which I believe the max that DLC can include was 200. That is what I remember being said.
When the new story content comes out this will be added by free DLC as the cap for a arcade game is 2GB which Ascend all ready is. so there is a high possibility that this will contain achievements and its adding to the story so I say it will.
