Guess you don't know how the back-end works in here.
From your title, you can see 2 sides:
1. The Dev Team, which has to deal with stability, optimizing, coding in abilities, moves, movepools etc.
2. The Content Team, which deals with creation of content, namely: regions, maps, stories etc.
And, the point of my text is: they run independent of each other in matters of creation. So you can expect the game to be turned back into Gold and Silver graphics without the Content Team knowing, or a brand new region to be added, without the Dev Team knowing.
