Josh Schwartz Tweets an ''Awesome'' Pic From the set of Chuck and Teases New Guest Stars?

Josh Schwartz - one of the executive producers on Chuck - has just posted this cool pic on his twitter account and wrote:

We have your actor. Sugarland gets to guest-star on #Chuck or next season just got a little less "Awesome"

The tweet's a bit cryptic but it seems that the band Sugarland will appear on the show. Maybe Jeffster could cover the first part of a concert for them!! How ''Awesome'' would that be?
