The popular real variety program, KBS’ 1 Night 2 Days will be going through some major changes, starting with a PD change.
On March 6, it was revealed through several KBS representatives that Choi Jae Hyung PD, aka Bird PD, as he′s called on the program, will be leaving the show. “It appears that Choi Jae Hyung PD will be leaving after the recording on March 15.”
Choi Jae Hyung PD’s replacement is currently under discussion, with Hello’s Lee Sae Hee PD named as a strong candidate. Lee Sae Hee PD has worked on Yoo Hee Yeol’s Sketchbook and Sang Sang Plus in the past.
With Choi Jae Hyung PD leaving the show, there may be some changes in staff and possibly the cast as well, but nothing is carved into stone as discussions for the show’s renovation are still taking place.
Choi Jae Hyung PD has been in charge of 1 Night 2 Days since March of 2012.

OP's thoughts summarized: Bird PD was nice but not right for the job, Joo Won might quit/get booted cause he NEVER TALKS, Kang Ho Dong should make a comeback.
