{Curiosity} Where did the original concepts end and new begin?

[MageBlack]

I've been curious lately to know where the original concepts, design, and system ideas end and where does the stuff Yoshi-P brought to the table begin?

Trying to recall 1.0, the GC ranks and such were part of the original ideas, so was group crafting (I remember pics of a huge birthday cake next to a lalafel chef). I also recall something about the current story we are going through was the original one for 1.0 but it was tweaked a little as well as put on hold to bring about the end of 1.0.

Was Golden Saucer all a part of that too, just put aside until it was ready? How about flying mounts? I think it would be really neat to see where these lines were drawn and where they have been blurred.

Thoughts? Input? Sources?

EDIT:

This is not meant to be a "Which is/was better" Simply where does one end and the other begin. I'm curious to know how long until all the content being developed will truly be "new". I think that once 3.0 comes that we will be truly into ARR. So far 2.0 feels like they have just been adding in all the stuff they wanted to have at launch. This team has said they are looking all the way into 4.0 right now for development, how far ahead was the old team looking?
