The ships were refreshed earlier in the year. The vehicle list hadn't been updated for a year or two, so was more important - plus the community requests for new vehicles. New entities generally depend on how fast the art team can make the new images, and with R&D coming soonish they may be redirecting their efforts to making images for such entities.
Any items added, would either be fluff, or require a coder to make an implementation for. Would rather just see custom items made, and save code time for other things.
Per ships, we just got a new set several months ago.
