What do you think it is that Luthier thinks will have Competitors squirming?

If it's a real jaw dropper then it's odd they couldn't hold off with the US release as it may have helped with sales?

As they didn't I imagine it will probably be something for mission builders, modelers or something and not something that the average player would use but which will definitely benefit the game in some way in the long run.
