Launch happens Tuesday, April 29th: game updates may be affected.

Sony Online Entertainment Community staff posted this update to the All-Access FAQ on all SOE game forums today:

Dear Players,

In an effort to ensure that the transition to the new All Access membership plan is as seamless as possible, we are going to be taking a little more time to test. So, we will be pushing the launch date of All Access to Tuesday, April 29th. Because of the portfolio-wide nature of this plan, this may prevent us from doing any individual game updates in EverQuest, EverQuest II, Planetside 2, and DC Universe Online. These updates will resume normally after the All Access launch. We appreciate your patience and you’ll agree that our new membership offering is worth the wait.

Short version: the new subscription plan will launch April 29, and EverQuest, EverQuest II, Planetside 2, and DC Universe Online may not see updates because of it.
