Where a whole new world is developing

The title of the post is the main subtitle for this years developer's conference. Obviously, you can take a lot of different things from these choice words. There is one thing that I really like about Apple and that is their clever command of the english language in their copywriting.

Some possible meanings:

- Obviously, at a developers conference, development will be discussed

- Whole new world, new ecosystem (TV, Watch, possibly)

- Whole new world, low cost iPhone for third world?

- Camera developing (I know, probably not :)

What do you guys think it means?
