Are there still gonna be worldwide servers?

Unfortunately for the people who share your desire, SE is more interested in perspective players, and you seem to be the minority. They did say that they will allow you to choose which server you want to play on, but no word of a server specifically targeted for people who want to play with people from other regions yet, and to be honest this is obviously only my opinion, but I doubt they will have one.

However, and this is speculation, it may be possible to group (via dungeon finder) and communicate with people who are on your friends list regardless of region. I have no evidence to suggest that's what they're planning, but I have seen it done this way in other MMOs.
