As quoted from Mike below:

"We hope to have the CAP set and new park stats up by Friday night. Before changes caused by park changes the CAP was estimated by Ken Grashoff to be:

24 team=87
20 team=77

John M will be refiguring the CAP based on average PB value for top 27 players currently on the rosters, once he has updated the stats to reflect the new park effects and other recent ratings changes."

So its supposed to happen, but my experience says that it really only affects the actual games you play, not the estimated stats. Then again its tough to prove one way or another.
