Dates... we don't have them. We are gamers! jk, the game is still in pre-alpha so it's definitely gonna take a while. As for playing it for free, you'll never be able to. You'll need to buy a Spark of Life which gives you 10-14 months of real world time to play and you'll lose some of that time each time you get killed ingame. Regarding pre ordering, you have the pledge packages in the store, i guess.
