Anyone started watching season 5 yet?

***SPOILERS FROM NOW ON***

Not sure of what's going on, but were those last five minutes of the first episode a trailer for what's coming up for the rest of the season, or was that an incredibly detailed, intricate and funny montage with no reference to anything?

Was a so-so start to the season, quite heavily plot based, but looks like it's setting up for a change in what's to come. Probably for the best, can't imagine what new they could do with the spy format for this season.
