This is all different because of David's 'Risk Rollout' plan for systems. He's rolling things out in terms of 'risk to development' so the first Alpha had the main 'how does it fly' as the main thrust. Alpha 2 was about multiplayer and Beta is about the trade cycle.
Unlike most developers FD aren't rolling out the slice of the cake with everything in place, mainly the 'high end' development work is what has been rolled out first. And filling in the lesser stuff as we go forward.
I'm paraphrasing and expect someone else can explain it better, but basically this is why their development cycle is so different to what some people are used to. Where Betas are essentially demos.
