Regretfully I'm not sure there was ever a plan overall. 3.0 and 4.0 were back in the day supposed to be released at the same time, everything feels like it's been thrown out the window between 2.0 and 3.0 and I believe Anno stated recently he hadn't even started 3.0 + 1.0. I hesitate, truly, honestly, to put it like this, but it really feels as though they're just making it up as they go along now as opposed to working to some grand pre-planned overarching plot.
