So, a brief summary:
According to every source known to Man, Major League Baseball and the Major League Baseball Players Association have agreed to expand the postseason, adding one "Wild Card" in each league. There are details, though. Scheduling details. And those details have not been resolved, which throws the whole enterprise into question. In 2012, anyway. Especially with a March 1 deadline looming.

And for our next trick, we will explain the difference between a deadline and a hard deadline.
It sure does seem like everybody wants this to happen in 2012, which makes me think it will happen in 2012. Which will make a lot of contending teams really happy, because if you're targeting 90 wins in March your chances of winning the World Series goes up significantly if you've got an extra chance at qualifying for the tournament.
