They've already announced how they're going to pick up where they left off and it's actually a very good idea.

For the first few episodes, each main character is going to get a recap episode of what they've been up to.

(Now my personal opinion:) Of couse, the other characters are going to show up but I think it's a very original catching up if they do it from each character's perspective. It will allow for a deeper understanding of their world and when they bring things back into a meld it will be that much more funny because of the conflicts set up in the first few episodes.

Totally agree. Where did you read that this was what is going to happen?

There was a panel a month or so ago ("Bluth Family Reunion", maybe?) in which Mitch Hurwitz said this. I don't remember where I watched it.
