The World Series is starting on a Wednesday and finishing in November.
This doesn't sound like such big news, but I think there could be a bigger story lurking in the background. All the media coverage seems to be focusing on the Wednesday start (good for baseball - ratings will increase), the November finish (bad, but is four days really that big a difference?) and to a lesser extent, the extra days rest in the earlier rounds.

The extra rest is a little troubling to me, but maybe it won't be permanent. Pushing the World Series back four days gives MLB enough room to expand the first round of the playoffs to 7 games. My hunch is that after a test run this offseason, MLB will talk to the union about expanding to 7 games next season. The schedule would work perfectly. All series would be 2-3-2 with days off after games 2 & 5. The two leagues could stagger their starts and still wind up with at least two games off before the World Series.

I think a switch to 7 games makes all the sense in the world. Obviously, God didn't divine that 7 is the perfect amount of games to deterine which team is superior, but it's clear that more games = less random. And I don't see any reason to make the first round outcome more random than the later rounds.
