This debate has been raging ever since, and the lack of a historical "railroad" event system (à la HoI2) in HoI3 is only adding to the fires.
What lack?
All the major historical events from hoi2 are now in.
Except you can now SEE the triggers for them and decide whenever you want to trigger them when they are possible.
(And the AI always does them as soon as they are possible)
