Just curious to know how frequently additions are made to the CP Exchange. I would hate to have saved CPs for months and months and exchange them for a ship or something the day before a major release of ships or other items are available.
Yes, that's what I thought too.
It's just that a month or so from joining, I remember the Longprobe was just introduced... so I was just curious to know if there would be planned updates to the list of stuff available.
No. There is no information on when or with what additions the CP exchange will next be updated. When said information is available you will find it on the Sim News, and until then, you may assume that no changes are planned for the foreseeable future.
