If you read the page, it says:
“Credits, Ships and Vehicles are now implemented. ”
When you're standing on a planet surface I recall it saying something about "all other exchanges are disabled at the moment." This was the same coding issue that was responsible for part of the delay in the CP droids.
Since there is a lot of work being done on making items work properly, and implementing an inventory for them, I imagine any CP items will be delayed until work is finished and we have full and proper functionality.
