Them?  For the last few weeks we've been hearing all about how 'Arrested Development' season 4 was bringing back fan favorite characters like Barry Zuckerkorn and Lucille 2 (seriously, we were this close to writing about bringing back the stair car), but what of the new faces?  Apart from the 'Workaholics' crew and 'Mad Men's John Slattery, what do pint-size beauty Isla Fisher and chiseled man-mountain Terry Crews have to offer 'Arrested Development' season 4?

In what's sure to represent a new benchmark in opposite-spectrum casting, 'Arrested Development' season 4 has added two new faces to its upcoming Netflix run, set to premiere its 10 (potentially 13) new episodes in the spring of 2013.  Zap2It first confirmed the news, though sadly, no details are available of either role.  Who wants to take bets on Isla Fisher as a new potential love interest of Michael's?

Fisher and Crews, who himself had a strong summer being featured in both 'The Expendables 2' and 'The Newsroom,' join returning series players Liza Minnelli, Judy Greer, Henry Winkler and Scott Baio.  As previously mentioned, the new season of ‘Arrested Development’ has recruited all three ‘Workaholics‘ stars as well as ‘Mad Men’s’ John Slattery for similarly unspecified roles.

What say you?  Who do you think Isla Fisher and Terry Crews might play in the forthcoming revival of 'Arrested Development?'  Are you looking forward to the new season?  Give us your reaction in the comments below!
