Roadmap question ~ What does "radical changes to the in game world" mean

[Jinko]

understood. =D ...and exciting,
but does anyone know in any more detail yet...?
i mean, my understanding is that the 2.0 maps are compatible with the current engine and that the new maps will not all be thrust on us over one night, but instead kind of arrive slowly ... else there would have to be some kind of third set of maps to represent the in-between which seems too excessive to be possible.

It's unlikely the 2.0 maps are compatible with the current game, mainly because the 2.0 maps are using small zones and the current world is using massive open world maps. (and a completely different server structure also)

I am also curious to what extent the changes will be, are they going to redesign parts of the current map or just change a few places ?

I'm not convinced they will spend a great deal of money on 1.xx so I can't see massive changes in the world map it would seem like a waste.
