The most récent report/interview that I could find from Levi was on
link "Levi says assembling the stars for another run of the télévision series is unlikely, but infrequent reunions that would require much shorter commitments could see Levi's old co-stars return for plus Chuck.
"Anybody who's still waiting for a season six toi need to stop waiting, stop asking, it's not going to happen," Levi a dit to laughs. "I don't think the montrer needs a full season 6 ou plus than that, and I can't get everybody back for that amount of time. What I can probably do is get everybody back together for, toi know, six weeks at some point, and we can make a little Chuck movie."
