I sent in a few questions to customer support here are the answers.
1) The current launch date is April 15.
2) There is no free trial, but there will be free trials in the future.
3) The game is in closed beta. We will open up the game to pre-order players as soon as possible.
4) The game is mostly based around player interactions, but as the game grows it will be more viable for solo players.
5) The game is not available in stores.
Hope this answers some questions others might have
