Depth in the context of a games is well known, perhaps you should look it up? It is no different then saying you want to see them flush out the current mechanics. But if you really don't understand what it means to have depth in a game, I will try to explain it to you.
Current scanning mechanics are just push a button, it has very little depth, it is shallow and does not take any effort on the part of the players. Same issue with CIG's golf swing mechanic. Now take EVE onlines scanning, it has depth, it takes skill to use and effort from the player. Crafting could be expanded as well, giving more options and more branches.
Well I disagree and let me explain. Every game has development focus. Some hardcore games like to have complex mechanisms to for you to turn knobs, do lot of quite useless tasks to get one final task done. Some people like that and they like to use word "depth" instead of "complex", because it sounds better.
In reality it is different focus. ED focus is not to make scanning complex, certainly at rude level. Scanning of the ship is very simple thing, yet in combat it is annoying and people already complain it takes time and they shoot and they get bounties.
It is my personal opinion that "depth" is really used against simplistic mechanisms because of "more sim like games" have it - games does not work really like that.
Current mission system is basic and does not have co-op missions, you could add depth to the mission system by adding co-op missions.
There's no depth in co-op missions, you just automatically share spoils of war with others.
Adding depth to the current base game would be expanding on the activities you done while piloting a ship. Sure FD added ground missions but again they ended up being shallow and needed expanding on.
They are not shallow, they are quite complex last time I tried. There are good reason why I haven't done them much yet.
Said all that - it does not mean gameplay does not have to get better in ED. It does, in multitudes, but I am afraid it won't be that 'depth' you are looking for. Moment by moment gameplay has to be interesting, engaging yet simple enough to make people play for considerable time, otherwise only hardcore will play ED.
edit: just for SC example all golf swing scanning is just pure example of there being strong disconnect between actual game being developed and people expecting it to be at hardcore level of EvE or even flight sims. It can't be all of those things. If they will want to earn money, scanning will be simple and you won't need 2 hour course to train for it.
