I reckon the absolute earliest time to get the new MBP's will be 12th/13th June... For example it gets revealed on 11th and gets put on the site for sale straight away
Me too.
By the way, where are the new iMacs? It's been 384 days since Apple last refreshed the iMac. And the new desktop Ivy Bridge processors and mobile AMD video cards are already out. I can understand that the new MacBook Pros and Airs were not released yet because no dual core Ivy Bridge mobile processors have been released yet... but what about the iMac? What is Apple waiting for?

In Oct. 2008 Apple released the Macbook Pro with the unibody design and there was no press release. The last macbook pro released at WWDC was June 2009 but that does not mean history will repeat.
It was not a press release, it was a media event when Apple released the unibody MacBook line. Look here: https://www.macrumors.com/2008/10/09/apple-invites-media-to-notebook-event-october-14th/
