Please help me decide. Will AB 2 make AB obsolete? Is it really worth buying the complete collection of AB at this time, given the fact that AB 2 is going to be released in 2025?

Is it helpful to play and learn AB1 to help the learning curve for AB2?

The trailer is showing some pretty neat real life looking game footage. Is that part of the game or is it just not part of the game? A trailer should make it clear what is part of the game and what is not. We want to know what we are buying.

Is there a tutorial scenario or small scenario to help learn the game?

I am fighting my first defensive battle and somehow the enemy know where all my units are. This would make sense if they could see me, but my entire force is in a forest. So I am not sure how they know where I am. Is it because I am on the edge of the Forrest?...
