Probably around the same amount of people if you take in account of the people who will eventually git bored of the game, goes away due to real life events like new child or military deployment, yet more will take their place such as 9 year old trollers that haven't been born yet right now and other finding out about this game through a variety of reasons.

Graphics will likely be realistic and 3D to the point that your in the animation itself where holographic representations of your friends, enemies, and environment will surround you.

Annnnd of course all bacon will be awesome as always.

Hahaha clever... no no no you're not baiting me into divulging my complete list.

In 10 years I Dust will be established enough to inspire a creative renaissance in the failing FPS genre. Dedicated CoD players will wake up from their dreams of instant gratification provided by Activision, forcing them to finally change their formula to adapt, or be left behind in the growing competition. Classic IPs will be revived, rebooted, bringing back beloved features from their treasured heritage while adding a new age spin that will be accepted by gamers, young and old. Players will be rewarded for exploring maps for hidden areas instead of being lead on a series of rails with cutscenes and quick time events to break up the mindless monotony. Doom, Quake, Wolfenstein, SOCOM, and Rainbow Six will be household names again, warranting relevance when the current leader of the NRA brings them up to defend the right to bear arms. These won't be just good times for Dust, but good times for competitive gaming!

Wow, I think I got lost in the moment for a second...

Anyway, Dust should probably be at a point where all the potential we all are hoping for now will be reached. Planetary Conquest will be as cutthroat as ever with all the meta gaming drama that we hear horror stories about in EVE. Spying, treachery, corporate scandals, piracy and all out war that won't just be limited to fighting on planets that for some reason share different variations of Line Harvest, Ashland, Manus Peak, Skim Junction, and "The Complex." Titan class ship pilots will have more to be afraid of when a lone enemy Frigate manages to break through their convoy and launch a set of pods full of mercenaries that will fight their way into the monolith of a ship to it's core, blowing it up from the inside out.
