The final image there suggests to me they might be teasing a full logo redesign rather than just a jersey redesign. I guess we will see.
For my part, I have no particular feelings about the "script" Kings jerseys. There's nothing wrong with them, but they don't jump out at me as particularly attractive either.
Honestly, I wouldn't mind seeing an overall logo redesign that includes The Beam - sure, it's a gimmick, but it's fun and recognizable. And while The Beam obviously can't last forever, after just one season it's iconic enough to be identified with the team. We're already in a position where the Kings probably can't just "stop" doing The Beam, they have to "officially retire" it when its time is up. Incorporating it into the logo would give it a sort of natural shelf life...once the next logo redesign was due, it could easily be officially retired along with the previous logo or, if The Beam isn't stale yet, could be kept through another logo cycle.
