From what I've read, the 'W' in the name probably stands for its increased focus in World news, but also on health and finance judging by the new titles. The weekend morning news in KBS1 is also changing in June, from two newscasts at 6 and 8 to one at 7:

From the 29th, KBS will increase news content and change the broadcasting time of entertainment programs through a reorganization in the first half of the year.

KBS 2TV presents a new comprehensive news program, 'KBS News 6', Monday through Thursday at 6:00 PM. 1TV plans to provide international current affairs information by establishing 'KBS Newsline W'. News times are also shifting. From June 11, 1TV's 'Sunday morning 7 o'clock news' replaces the 6 and 8 o'clock news, and delivers weekend morning news.

The live current affairs talk show 'The Live' will be expanded to 60 minutes and moved to 2TV. 'The Live' will increase the broadcasting time to deal with the issues of the day in depth, and further strengthen the aspect of 'current affairs entertainment' in line with the nature of the 2TV channel. The new 'The Live' will be broadcast for the first time on June 12th.
