My guess is that they're waiting to put all of the offers and perks out to people after they see who is genuinely interested in moving to Sweden during the trip. I'd give them until a week after that before I started worrying too much.

Wow, it sounds like you're going to be quite busy for most of this year, especially if you move. I hope you do get the chance to go to your friend's wedding in Boston, I hear it's an interesting city.

Have fun at P4! I'm envious.
